Definition of the primary structure of a protein

Answers

Answer 1
The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.

what are the different parts of microscope ?

A microscope is which produces large images of tiny  substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope consist of  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base of microscope is used to support  and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are basically applied for the  view, magnify, and production of an image from a specimen placed and the various parts.

Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

What is the use of reverse transcriptase?

Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.

Therefore, The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

QUESTION 9
if a woman who is a carrier for Fragilex syndrome (an X-linked disorder) has children with a man who does not have the disorder, what chance do their
daughters have of being carriers of Fraglese
None
50%
25%
100%

Answers

Answer:

Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.

Explanation:

Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.

In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).

Cross X x XY

Alleles         X           Y

[tex]X^{f}[/tex]            [tex]X^{f}[/tex]X       [tex]X^{f}[/tex]Y

X               XX          XY

The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

Explain how 1st and 2nd law of thermodynamics applies to the trophic structure of an ecosystem?​

Answers

Answer:

First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels

Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.

Explanation:

The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.

In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.

When the concentration of molecules on both sides of a membrane is the SAME, the solution is

Answers

Answer:

When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.

Explanation:

A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.

The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.

An isotonic solution does not generate gradients, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.

A. Modern camels share an evolutionary relationship with Aepycamelus, but they didn’t directly evolve from them.

Explanation:

The phylogeny chart shows that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them

What is a phylogeny chart?

A phylogeny chart is a chart that shows the relatedness of organisms by charting structural relationships in order to determine their evolutionary origins.

From the phylogeny chart , modern camels, Camelus share an evolutionary relationship with Aepycamelus as they both originate From a common ancestor, Protylopus.

However, modern camels do not directly originate from Aepycamelus.

Therefore, it can be concluded that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them.

Answer:

pyruvate

Explanation:

In glycolysis, the 6-carbon sugar, which is glucose, is broken down into two molecules of a 3-carbon molecule called pyruvate.

During glycolysis, glucose is broken down into ; Pyruvate molecules  and energy

Glycolysis is a cytoplasmic process during which glucose is broken down into two  3 carbon compounds ( pyruvate ) and energy is generated from t glucose in the process.

The breakdown of glucose during glycolysis is as represented below

Glucose + 2 NAD⁺ + 2ADP + 2Pi ----> 2 Pyruvate + 2 NADH + 2 H⁺  + 2ATP  + 2 H₂O

Hence we can conclude that During glycolysis glucose is broken down into ; Pyruvate and energy.

Why is it important to have a control group in the experimental design?

Answers

The control group is the main one because it acts as a benchmark to balance the results of the experiment.

What is control group in the experiment?

Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.

So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.
