Meaning and Origin:
Plasmids are small, circular, double-stranded DNA molecules that are non-essential (accessory) to the chromosomal DNA of a cell. They are found in bacteria, archaea, and some eukaryotes. Plasmids carry genes that typically provide an advantage to the host organism, such as antibiotic resistance, metabolic pathway enhancements, or virulence factors.
The term plasmid was originally coined by researchers studying genetic exchange in bacteria. In the 1950s, it was observed that certain genetic material could be transferred from one bacterial cell to another through a process called conjugation. This extrachromosomal DNA was found to be distinct from the chromosome and was given the name "plasmid."
Over time, the term "plasmid" has been expanded to include similar DNA molecules found in archaea and eukaryotes. Plasmids are now recognized as important genetic elements that contribute to the evolution and adaptation of organisms.
