An expression vector requires all of the following except
A) genes for ribosomal RNA.
B) a reporter gene.
C) a promoter of transcription.
D) an origin of DNA replication.
E) restriction enzyme recognition sequences.

Question

Quizplus · Accepted Answer

An expression vector does not require genes for ribosomal RNA as these are naturally occurring in the host cell. The other components listed (reporter gene, promoter of transcription, origin of DNA replication, and restriction enzyme recognition sequences) are necessary for the efficient expression and replication of the vector in the desired host cell.
