Plasmids are used as cloning vectors in genetic engineering. This means that plasmids allow for
A) carrying of RNA into a cell and RNA replication.
B) infection of cells.
C) carrying of DNA into a cell and DNA replication.
D) DNA replication outside rather than inside cells.

Question

Quizplus · Accepted Answer

Plasmids are small, circular DNA molecules found in bacteria that can be easily manipulated and used as vectors to carry foreign DNA into cells. Once inside the host cell, the plasmid can replicate along with the cell's own DNA, leading to the production of many copies of the desired DNA sequence. Therefore, plasmids allow for the carrying of DNA into a cell and DNA replication. Options A, B, and D are incorrect as they do not accurately describe the role of plasmids in genetic engineering.
