Genes have multiple alleles that differ in DNA sequence because a gene consists of many nucleotides, each of which can be any of four types.

Question

Genes have multiple alleles that differ in DNA sequence because a gene consists of many nucleotides, each of which can be any of four types.

Quizplus · Accepted Answer
