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 …

Mar 13, 2022 · The term Plasmid was coined by Joshua Lederberg in 1952. Plasmids are important as genetic tools, which are used to introduce, manipulate or delete certain genes from the host cell.

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, …

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 …

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 …

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 …

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.

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 …
