Changes That are Introduced into the DNA Strand During Replication

Question

Changes that are introduced into the DNA strand during replication are known as:
A) Codons
B) Phenotypes
C) Genotypes
D) Mutations
E) Errors

Accepted Answer

Changes introduced into the DNA strand during replication are known as mutations. Codons refer to specific sequences of three nucleotides that code for a specific amino acid. Phenotypes refer to the physical and observable characteristics of an organism. Genotypes refer to the genetic makeup of an organism. Errors is not an official term used in genetics, and is too general to accurately describe changes during DNA replication.
