episome उदाहरण वाक्य
उदाहरण वाक्य
अधिक: आगे- It maintains the viral genomes during cell division by tethering the viral episomes to the chromosomes.
- Other betaherpesviruses establish latency as a nuclear episome, which is a circular DNA molecule ( analogous to plasmids ).
- In eukaryotes, episomes are used to mean non-integrated extrachromosomal closed circular DNA molecule that may be replicated in the nucleus.
- A few types of plasmids can also insert into the host chromosome, and these integrative plasmids are sometimes referred to as episomes in prokaryotes.
- Normally, the virus exists as circular episome ( or plasmid ) within the cell and its DNA is packaged into viral capsids and transmitted to other cells.
- The Hirt extraction process gets rid of the high molecular weight nuclear DNA, leaving only low molecular weight mitochondrial DNA and any viral episomes present in the cell.
- As explained here, they're based on the F episome ( F plasmid ), but as our article explains, they do have the Rep gene.
- During latency, the virus genome depends on the host replication machinery and replicates as closed circular episome ( " plasmid " ) using sequences within the terminal repeats as a replication origin.
- When the virus reactivates into lytic replication, it is believed that the virus genome is replicated as a continuous linear molecule off from an episome ( so called rolling circle model ).
- Some viruses are tumorigenic when they infect a cell and persist as circular episomes or plasmids, replicating separately from host cell DNA ( Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus ).
