There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.

6a. The mRNA code for each type of amino acid is a

sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)

6b. In the figure, which mRNA codon codes for the amino acid Phe?

Answers

Answer:

The mRNA code for each type of amino acid is a  sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.

Explanation:

The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:

An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.

A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.

Phenylalanine (Phe), according to the image, is formed with the UUU codon.

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

Compare and contrast lactic acid fermentation and alcoholic fermentation. Include examples of organisms that use each type of fermentation.

Answers

Answer:

Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.

Explanation:

The comparison between lactic acid fermentation and alcoholic fermentation-

1. Lactic Acid Fermentation:

pyruvate changes to lactic acidused by muscle

2. Alcoholic fermentation:

pyruvate changes to alcohol and carbon dioxideused in bread by yeast, wine, and biofuels

Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into ATP which is cellular energy and the metabolite lactate, which is the lactic acid in solution.

Alcoholic fermentation is a biological process by which sugar is converted into alcohol and carbon dioxide with heat.both happen under anaerobic conditions and produce a little amount of ATP.Alcoholic fermentation gives CO2 while lactic acid does not.

Write a chemical equation for cellular respiration. Label the molecules involved.

Help!

Answers

Answer:

C6H12O6(glucose) + 6 O2(oxygen gas) ---> 6CO2(carbon dioxide gas) = 6 H2O (water) + ATP (energy)

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is cellular respiration?

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.

Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.

Disorders that interfere with cellular respiration typically affect one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.

Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna

Answers

Answer:

C

Explanation:

The correct answer would be that more closely related species will have more similarities in DNA.

The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.

The correct option is, therefore, C.

Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.

The correct answer is:

Option C. More closely related species will have more similarities in DNA

The DNA stores the genetic information of the organisms and codes for the traits of the organism.

The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.

The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.

Therefore, option C is correct.

Hope this helps.

A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.

What are cell organelles?

Cell organelles are the ultrastructure's present in the cell and they show division of labor.

These organelles perform specific function for the cell and thus constitute the framework of all living organisms.

The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.

Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.

Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.

Cell organelles are thus important structural and functional elements of a cell.

RNA polymerase is used to add new RNA nucleotides to produce RNA.

RNA polymerase

It is the enzyme responsible for copying the sequence of DNA into the sequence of RNA during the process of transcription.

The information encoded in DNA is used to produce RNA during the process of transcription.

The production of RNA takes place by the enzyme RNA polymerase, by using the antisense strand of the DNA as the template by supplementing the complementary RNA nucleotides to the 3 prime terminal of the developing strand.

The enzyme RNA polymerase combines with the DNA at a sequence known as the promoter at the time of the beginning of transcription.
