E) resemble the phosphate groups found in DNA nucleotides.

Question

Quizplus · Accepted Answer

Base analogs are compounds that can substitute for the normal nucleobases in nucleic acids but often pair incorrectly during DNA replication, leading to single-nucleotide substitution mutations, rather than frameshift mutations, sugar or phosphate group mimicry, or DNA strand breakage.
