Definition of episome in English English dictionary
- A segment of DNA that can exist and replicate either autonomously in the cytoplasm or as part of a chromosome, mainly found in bacteria
- Any of a group of genetic elements consisting of DNA and capable of giving selective advantage to the bacteria in which they occur. Episomes may be attached to the bacterial cell membrane or become part of the chromosome. Cells with episomes act like males during conjugation, a mating process in certain bacteria. During conjugation, cells lacking the episome may receive either the episome or the episome plus the genes to which it is attached. Experiments involving gene transfers from cells in which episomes have been incorporated in the chromosomes have been used to determine the locations of genes on the chromosome
- A plasmid able to integrate into bacterial DNA
- A plasmid that can exist either independently in the cytoplasm or as an integrated part of the genome of its bacterial host
- A part of a gene
- A genetic element in bacteria that can replicate free in the cytoplasm or can be inserted into the main bacterial chromosome and replicate with the chromosome Term used by Jacob and Wollman for genetic elements that can either exist independently in a cell or become integrated into the host chromosome
- Plasmid that replicates by inserting itself into the bacterial chromosome
- episomal
- Pertaining to an episome or DNA fragments not contained within a chromosome
