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 …

Plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains. Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate independently of the …

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.

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.

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

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 …

Plasmids are the workhorses of molecular biology. Plasmids are small, circular DNA molecules that replicate independently of the chromosomes in the microorganisms that harbor them. Plasmids are …

What is a Plasmid? Definition of Plasmids: Plasmids are small, circular DNA molecules. They exist separately from the main DNA in cells and can copy themselves. They are predominantly found in …

A plasmid is a closed circular molecule of double-stranded DNA that range in size from 1 to >200 kb. Plasmids are found in various bacterial species, where they behave as additional genetic units …
