5 Questions
What is a plasmid?
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently.
Where are plasmids most commonly found?
Plasmids are most commonly found as small circular, double-stranded DNA molecules in bacteria.
How are artificial plasmids widely used in molecular cloning?
Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms.
What benefit do plasmids often provide to the organism in nature?
Plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance.
How are plasmids introduced into a cell in the laboratory?
Plasmids may be introduced into a cell via transformation in the laboratory.
