In a prokaryote, a group of genes with related functions, along with their associated control sequences, defines
A)an allele.
B)an operon.
C)a locus.
D)a transposon.

Question

Quizplus · Accepted Answer

In a prokaryote, a group of genes with related functions, along with their associated control sequences, define an operon. An operon is a cluster of genes that are transcribed together as a single mRNA molecule, and the control sequences regulate the expression of the entire operon as a unit. Examples of operons include the lac operon and the trp operon, both of which regulate the expression of genes involved in sugar metabolism and amino acid biosynthesis, respectively. Therefore, option B is the correct choice.
