Following antigenic stimulation, phosphorylation of _________ relieves inhibition of the transcription factor

Answers

Answer: zap70, ITAM.

Explanation:

An antigen is any substance that is capable of stimulating an immune response by activating lymphocytes, which are the body’s infection-fighting white blood cells. Examples of antigens could be proteins that are part of bacteria or viruses or components of serum and red blood cells from other individuals, all of them are foreign antigens originated outside the body. However, there can also be autoantigens (which are self-antigens), originated within the body. In normal conditions, the body is able to distinguish self from nonself. And the antigens that represent a danger induces an immune response by stimulating the lymphocytes to produce antibody or to attack the antigen directly. This is called an antigenic stimulation of the immune system.

ZAP-70 (Zeta-chain-associated protein kinase 70) is a protein that is part of the T cell receptor, thereby it plays a critical role in T-cell signaling. When the TCR (receptor of T cells) is activated by the presentation of the specific antigen through the MHC, a protein called Lck acts to phosphorylate the intracellular CD3 chains and the ζ chains of the TCR complex, allowing the binding of the cytoplasmic tyrosine kinase, ZAP-70. Lck then phosphorylates and activates ZAP-70, which in turn phosphorylates another molecule in the signaling cascade called LAT (short for Linker of Activated T cells), a transmembrane protein that serves as an anchor site for several other proteins. The tyrosine phosphorylation cascade initiated by the Lck culminates in the intracellular mobilization of calcium ion (Ca2+) and the activation of important signaling cascades within the lymphocytes. These include the Ras-MEK-ERK pathway, which is based on activating certain transcription factors such as NFAT, NFκB and AP-1. These transcription factors regulate the production of of certain gene products, most notably cytokines such as interleukin-2 that promote the long-term proliferation and differentiation of activated lymphocytes.

The ITAM motifs (immunoreceptor tyrosine-based activation motif) are sequences of four amino acids present in the intracellular tails of certain proteins that serve as receptors within the immune system. Thus, some receptors such as the TCR have ITAM sequences that, when activated, trigger an intracellular reaction based on consecutive phosphorylations.  Kinases are recruited for this purpose.

So, ZAP-70 is a protein tyrosine kinase with a role in T-cell receptor signal transduction. During T-cell activation, ZAP-70 binds to ITAM and becomes tyrosine phosphorylated. The binding of ZAP-70 to the phosphorylated ITAM is able to activate its kinase activity, and relieves the inhibition of the transcription factor which regulates genes that are involved in the immune reaction.

We can find four principal layers composing the digestive tube walls. From the lumen to the exterior: Mucosa, Submucosa, Muscle, and Serosa Layers.  

-----------------------------

There are four principal layers composing the digestive tube walls.  

From the lumen to the exterior of the tube, we can find,

Mucosa Layer

Composed of lining epithelium, a propria lamina of connective tissue, and a smooth muscle layer.

The epithelium works as a barrier that separates the lumen from the organ.

Propria lamina has glands, vessels that get the absorbed substances, and immune system elements.

The smooth muscle delimitates the mucose from the submucosa layer. It produces movements that are independent of the rest of the organ's movements.

Submucosa Layer

Dense connective tissue is placed under the mucosa.

It has bigger vessels that ramification to the mucose, muscle layer, and serosa layer.

In certain areas, this layer also has glands.

Muscle Layer

Composed of two or three concentric smooth muscle layers that differ in their orientation.

The contraction of these layers mixes and propels the content of the lumen of the digestive tube.

Serosa layer

Connective tissue membrane covered by simple plane epithelium.

High caliber vessels are placed in this layer and limphatic vessels.

There are regions of the digestive tube where there is no serosa layer. Instead, there is a connective tissue named the adventitious layer.

Explanation:

Knowledge of the driver mutations underlying cancer has led to targeted therapeutics, such as the protein kinase inhibitor imatinib (trade name Gleevec) in cases of chronic myeloid leukemia. Cancer cells often become resistant to a given drug, so researchers continue searching for new drugs that target proteins that contribute to the cancerous phenotype. One recent promising approach uses drugs that lead to ubiquitination and proteasomal degradation of the target protein. Which of the following mutated proteins are good candidates for this approach?
A) oncogenes
B) proteins with loss-of-function mutations
C) proteins with gain-of-function mutations
D) tumor suppressor genes

Answers

Answer:

C) proteins with gain-of-function mutations

Explanation:

Gain-of-function mutations: In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".

In the question above, the correct answer is option C.

Answers

Answer:

The correct answer is intragenic suppressor mutation.

Explanation:

A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.  

On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.

TRBP is a protein important for the formation of the RISC complex. Which of the following would you expect in cells with null mutations in TRBP?
a. Reduced siRNA-mediated mRNA degradation
b. Increased miRNA-mediated translational repression
c. Increased deadenylase-mediated mRNA degradation
d. Reduced proteasome-mediated protein degradation

Answers

Answer:

a. Reduced siRNA-mediated mRNA degradation

Explanation:

The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.

Based on the data table below, which number would be the BEST choice for the top number of the scale on the vertical axis of a scatter plot showing this data?

Answers

Answer:

D. 70

Explanation:

From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.

If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).

Distance would be in the vertical axis, while time would be in the horizontal axis.

Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.

Describe how scent and taste work in conjunction. Are the tastes of below mention foods that were tested heightened by the sense of smell, or only some of the foods?

a. Salt
b. Sugar
c. Lemon Juice
d. Coffe grounds

Answers

Answer:

Scent and Taste work in conjunction because when your brain smells food, it pulls up a picture or memory of that food in your head, and you remember what it tasted like and if you enjoyed it.

Only some of the food. Salt does not really have a smell, so it does not do anything, but all the others do and are heightened

Explanation:

Take cotton candy for example. When you smell cotton candy, you smell SUGAR and lots of it. You know that sugar tastes good and as such you now want to eat the cotton candy.

For this example, we will use lemonade. Lemonade is commonly a drink that most love on a hot summer day at the beach. When you smell the lemonade, it reminds your brain of how good it tasted and pulls up the memory at the back of your mind,  making you feel happy and relaxed. It then ends up tasting better

(This is my first answer, it won't be perfect)

Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.

What is Conjuction?

Since salt doesn't truly have a fragrance, it has no effect; nevertheless, all the others do and their intensity is increased.

You can definitely smell a lot of sugar when you smell cotton candy. You want to eat the cotton candy because you are aware that sugar tastes delicious.

On a hot summer day at the beach, most people enjoy drinking lemonade.

Answers

Answer:

Hydrophilic portions are outside and hydrophobic regions are inside

Explanation:

A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

g UV radiation causes covalent dimerization of two subsequent ______ bases in DNA. This dimer is recognized and repaired by ______.

Answers

Answer: The options are not given.

Here are the options.

a. C and C ;;;; DNA photolyase

b. T and T ;;;;; DNA photolyase

c. C and C ;;;; DNA photoisomerase

d. T and T ;;;;; DNA photoisomerase

e. None of the above

Explanation:

UV light damages the DNA of cells that are exposed by making bonds to be formed between adjacent pyrimidine bases, usually thymines, in the DNA chains. The thymine dimers inhibit or hinder the DNA correct replication during reproduction of the cell.

UV radiation causes covalent dimerization of two subsequent T and T because Thymine bases of DNA directly absorbs a UVB photon . UVB light causes thymine base pairs close to each other in genetic sequences to bond together into pyrimidine dimers, thereby causing a disruption in the strand, which reproductive enzymes cannot copy.

UV-induced thymine dimers can be repaired by photoreactivation, in a process where energy from visible light is used to split the bonds forming the cyclobutane ring through the action of DNA photolyase, an enzyme that repaired damaged cause by uv radiation to dna.

he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.

Answers

The correct answer is A. An infection that migrates via the bloodstream

Explanation:

Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.

For the cells of the body to function properly, blood pH must be maintained between 7.35 and 7.45, a very narrow range. Buffer systems, the respiratory system, and the kidneys work together to help maintain acid-base balance.
