After many cell divisions, a segment of DNA has more base pairs than it originally did. Make a claim about how this could happen. Summarize evidence to support the claim and explain your reasoning.

It could happen through mutation

Explanation:

A segment of DNA after many cell divisions could have more base pairs than it originally did as a result of mutation.

Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:

Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.

the answer would be d

equal distribution i think.
