Episome - Wikipedia
An episome is a special type of plasmid, which remains as a part of the eukaryotic genome without integration. Episomes manage this by replicating together with the rest of the genome and subsequently associating with metaphase chromosomes during mitosis.

2024年11月7日 · Episome, in bacteria, one of a group of extrachromosomal genetic elements called plasmids, consisting of deoxyribonucleic acid (DNA) and capable of conferring a selective advantage upon the bacteria in which they occur.
What is the Difference Between Plasmid and Episome
2019年8月5日 · The main difference between plasmid and episome is that plasmid does not integrate into the genome, whereas episome can integrate into the genome. Also, plasmids mainly occur in prokaryotes while in eukaryotes, episomes behave as plasmids in prokaryotes.
Episome - an overview | ScienceDirect Topics
Episome maintenance is an essential part of the life cycle of the persistent DNA tumor viruses KSHV, EBV, and HPV. Disruption of episome maintenance can deregulate many aspects of the viral life cycle, including gene expression, DNA replication, and genome segregation.
Difference between Plasmid and Episome - BYJU'S
The differentiating factor between plasmid and episome is that plasmids do not integrate into the genome, while the episome can integrate into the genome. In addition, primarily, plasmids can be seen in prokaryotes whereas, in the eukaryotes, the …
Episome - an overview | ScienceDirect Topics
Episomes or plasmids are lengths of DNA existing either in the cytoplasm or attached to the chromosome of a bacterium: they replicate in synchrony with the bacterial chromosome, and are thus perpetuated as long as the parent strain exists. You might find these chapters and articles relevant to this topic.
Episome - an overview | ScienceDirect Topics
‘Episome’ is an antiquated term used to describe plasmids or bacteriophages which can reversibly integrate into a bacterial chromosome. From: Brenner's Encyclopedia of Genetics (Second Edition), 2013
Episomes and Transposases—Utilities to Maintain Transgene …
In lytic infections, binding of the viral origin binding protein (OBP) to the lytic origin of replication (ori-Lyt) initiates a rolling circle amplification of the EBV genome. In latent infections, the EBV genome is maintained in infected cells as an episome with approximately 2–20 copies per cell.
Episomes, Plasmids, Insertion Sequences, and Transposons
An episome is a non-essential genetic element. In addition to its independent existence, an episome can also exist as an integrated part of the host genome of bacteria . It originates outside the host, in a virus or another bacterium.
Episomes - SpringerLink
A small circular DNA molecule (the episome) undergoes a reciprocal crossover with the chromosome. No material is discarded in the process. All genetic information of both chromosome and episome is preserved in the new, composite structure.
