For a prokaryotic vector to be propagated in a host bacterial cell, the vector needs
A) an origin of replication.
B) telomeres.
C) centromeres.
D) drug-resistance genes.
E) reporter genes.

Question

Quizplus · Accepted Answer

An origin of replication is necessary for a vector to be replicated and maintained in a host bacterial cell. Telomeres and centromeres are only found in eukaryotic cells and are not necessary for prokaryotic vector propagation. Drug-resistance genes and reporter genes may be present in a vector, but they are not essential for propagation in a host bacterial cell.
