Question

A change in the DNA sequence by adding, deleting, or rearranging one or more nitrogen bases is called a _________.

Answer 1

A change in the DNA sequence by adding, deleting, or rearranging one or more nitrogenous bases is called a Point Mutation

Explanation:

Error during DNA replication can give rise to point mutation which is of the following types- Substitution mutation and Frameshift mutation.

Here the more appropriate form of mutation will be frameshift mutation where, because of addition, deletion or rearrangement of the nitrogenous bases, the reading frame of the codon or the three nucleotide bases together will shift from its original frame.
