Plasmid Diagram of a bacterium showing chromosomal DNA and plasmids (Not to scale) A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal …

2 days ago · A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently.

Oct 14, 2025 · plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains. Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate …

Jan 14, 2014 · What is a plasmid? At their most basic level, plasmids are small circular pieces of DNA that replicate independently from the host's chromosomal DNA. They are mainly found in bacteria, …

Oct 4, 2025 · Once a gene is incorporated, the recombinant plasmid can be introduced into host cells, typically bacteria, for replication. This process allows for the production of numerous gene copies or …

Apr 7, 2019 · A plasmid is a small, circular piece of DNA that is different than the chromosomal DNA, which is all the genetic material found in an organism’s chromosomes. It replicates independently of …

Aug 23, 2025 · A plasmid is a small, circular, extra-chromosomal DNA molecule found within the cells of many microorganisms. Unlike the main chromosomal DNA, which carries the fundamental genetic …

Apr 12, 2010 · A plasmid is an independent, circular, self-replicating DNA molecule that carries only a few genes. The number of plasmids in a cell generally remains constant from generation to generation.

Feb 17, 2025 · A plasmid controls its own replication by using the biosynthetic machinery of its host cell to make other plasmid-encoded protein molecules or materials that are needed for a particular function.

Dec 4, 2023 · A plasmid is a small circular piece of double stranded DNA that can replicate independently from a host’s chromosomal DNA. A plasmid is distinct from a cell’s chromosomal DNA …
