What is the Consequence of a Transversion Mutation in Duplex

Question

What is the consequence of a transversion mutation in duplex DNA?
A)A purine is replaced by a pyrimidine, and a pyrimidine is replaced by a purine.
B)A base pair is lost within the DNA of a gene, which causes a reading frameshift.
C)A purine is replaced by another purine, and a pyrimidine is replaced by another pyrimidine.
D)A base pair is added to the DNA within a gene, which causes a reading frameshift.
E)The sequence of the DNA remains the same since the change involves proteins.

Accepted Answer

A transversion mutation is a type of point mutation in which a purine (adenine or guanine) is replaced by a pyrimidine (thymine or cytosine), or vice versa. This change can have significant consequences on the structure and function of the resulting protein, potentially leading to genetic diseases or disorders. Options B and D describe insertion and deletion mutations, respectively, while option C describes a transition mutation, which involves a change from one type of nucleotide to another within the same group (purine to purine or pyrimidine to pyrimidine). Option E is incorrect because mutations occur at the DNA level, not the protein level.
