3 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 …

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 …

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

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 …

Oct 4, 2025 · These modified plasmids are used in molecular cloning, where specific genes are inserted into the plasmid structure. Once a gene is incorporated, the recombinant plasmid can …

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 …

Artificial plasmid or recombinant plasmid is the plasmid formed by recombining the bacterium’s DNA with desired DNA fragments. The process of transformation helps in introducing the DNA …

What is a Plasmid? Plasmids are small, double-stranded, circular pieces of DNA originally used by bacterial cells as a way to transfer traits, but are currently used in molecular biology to …

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 …
