Question

A chemical mutagen that is structurally similar to a nucleotide but has different base-pairing rules is called a ________.

Answer 1

Nucleoside analog

Step-by-step explanation:

• Nucleoside analogs are the mutagenic chemicals that have a structure that is similar to the normal bases of the nucleotide and thus can be incorporated in the DNA during the process of replication, however as it has different base-pairing rules than the normal nucleotide base it can lead to mutations.
• An example of a nucleoside analog is acyclovir which an analog of guanosine.
