Plasmids are
A) circular structures present in bacteria that contain genes encoding proteins and DNA and have the capacity to self-replicate and portion into daughter cells during cellular division.
B) DNA elements that encode transposition and excision function and can transpose from one place on the chromosome to another.
C) genetic elements capable of integrating resistance genes (cassettes) by an integron-encoded, site-specific recombinase.
D) DNA elements found in bacteria that carry genes only for the enzymes needed to promote their own transposition.

Question

Quizplus · Accepted Answer

Plasmids are circular DNA structures that are present in bacteria and have the ability to self-replicate and portion into daughter cells during cellular division. They often contain genes that encode proteins and other genetic material, and can play a role in genetic transfer between bacteria. Plasmids are not typically involved in transposition or site-specific recombination, which are distinct types of DNA elements with different functions.
