Plasmids are small, circular DNA molecules found in prokaryotic cells that replicate independently of chromosomal DNA. They often carry genes that confer advantageous traits such as antibiotic resistance.
5 Must Know Facts For Your Next Test
Plasmids can be transferred between bacteria through a process called conjugation.
They often contain genes responsible for antibiotic resistance.
Plasmids are used as vectors in genetic engineering to insert new genes into organisms.
Unlike chromosomal DNA, plasmids can replicate independently within the cell.
Plasmid replication is typically regulated by the origin of replication sequence they contain.
