C)telomere.
D)restriction enzyme.

Question

Quizplus · Accepted Answer

Plasmids are small, circular DNA molecules that are separate from the bacterial chromosome. They often contain genes that can provide the bacteria with advantageous traits such as antibiotic resistance or the ability to degrade unusual compounds. Vectors can include plasmids, but not all extrachromosomal DNA is a vector. Telomeres are the repetitive DNA sequences found at the end of eukaryotic chromosomes, and restriction enzymes are enzymes that cut DNA at specific recognition sequences.
