Changes in a Single Nucleotide Pair Within a Gene Is

Question

Changes in a single nucleotide pair within a gene is called
A)substitution.
B)translocation.
C)point mutation.
D)silent mutation.
E)evolution.

Accepted Answer

A point mutation is a change in a single nucleotide pair within a gene, which can include substitutions, insertions, or deletions. Translocation involves the movement of a segment of DNA from one chromosome to another, while a silent mutation does not affect the function of the gene. Evolution refers to changes in the genetic makeup of a population over time. Therefore, the best choice is C, as it accurately reflects the change in a single nucleotide pair within a gene.
