An mRNA that contains the coding sequence for two or more structural genes is called a
A)polyintronic mRNA.
B)polyextronic mRNA.
C)polycistronic mRNA.
D)polyexpressive mRNA.
E)polyrepressor mRNA.

Question

Quizplus · Accepted Answer

A polycistronic mRNA contains the coding sequences for two or more genes that are transcribed and translated as a single unit. This is common in prokaryotes and some viruses, but is not found in eukaryotes. The other answer choices are not used to describe this type of mRNA.
