What process will occur if an error is made during DNA replication, resulting in a slight change to the structure of a gene?
A. natural selection
B. combination
C. mutation
D. extinction

Answer 1

Answer: i believe it is mutation

Explanation: An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated (Figure 2). Strand slippage can also lead to deletion mutations.

Answer 2

Answer:

C. mutation

Explanation:

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation.
