Question

Identify the mutation and the effect it would have on protein synthesis.

Answer 1

Answer:

Explanation:

DNA mutations could be silent and have no effect, others affect protein synthesis. Mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage.

A point mutation is a single-letter swap – an exchange of two bases, adenine to cytosine, for example, at a single location in the DNA molecule. Since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein. Sometimes a change in the protein's amino acid sequence can have dramatic results. For example, sickle cell disease occurs when a single-point mutation in the gene that encodes the hemoglobin molecule results in deformed red blood cells.

Answer 2

Answer:

B) This mutation is a deletion mutation resulting in a frameshift. This would result in a different reading of the codons following the mutation, causing a different translation from the original strand. The protein being created could be abnormally short, abnormally long, and will most likely not be functional.
