Detailed explanation-1: -Definition. 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.

Detailed explanation-2: -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. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.

Detailed explanation-3: -Plasmids are rings of DNA –double-stranded molecules that hold genetic information – that are found in most bacteria.

Detailed explanation-4: -Plasmids carry genes for replicating their DNA, transferring themselves from one host cell to another, and for a variety of phenotypes. Many plasmids carry genes that confer antibiotic resistance on the host cell when the genes are expressed.

Detailed explanation-5: -A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.
