Mutation occurs and the GGA coden is changed to GGA. What effect does the substitution have on the amnio acid?

Biology
1 answer:
dlinn [17]3 years ago
5 0

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

In 1953, Stanley Miller and Harold Urey built a model of Earth's early
ExtremeBDS [4]

Answer: C. Miller and Urey showed that inorganic compounds could combine  to form the building blocks of living cells.

Explanation:

The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.

The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.

If polar is positive and non-polar is negative then why can’t a polar molecule pass through the non-polar phospholipid membrane
Ierofanga [76]

Answer:

Because of the chemical and structural nature of the phospholipid lipid by layer the lipid soluble molecule can just pass the lipid membrane and some small molecules can also pass freely.

Explanation:

as we know that the homeostasis is an important process for a  living cell to maintain it self so for the the exchange of materials between the external and internal environment is must so for that it exchange material with the outside environment of the cell.as the cell membrane is semipermeable(mean allow some molecule to pass(lipid soluble) and not others(lipid non soluble) to pass through the membrane.the cell membrane is selectively permeable due to its nature and chemical composition the chemical composition is lipid and  phosphate and glycerol(head) with fatty acid that may b saturated or unsaturated(tail).so finally all those molecule which are polar can not pass through the membrane and  non polar can pass the membrane.The size of the molecule is also a factor on which the permeability depends.

What challenges do you think parasites face in their survival? How can these challenges affect the parasite?
Greeley [361]
Parasites need a host. If a host tries to get rid of the parasite or kill it, then the parasite either has to leave the body or die.

A cell with 22 chromosomes undergoes mitosis. How many nuclei result from this process?
kondor19780726 [428]

Answer:

Explanation:

Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus.
