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 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 …

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 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.

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.
