Histone modifications are the influencers of zygotic genome awakening

The zebrafish is an important model organism in biology. Humans and zebrafish share 70 percent of their genes, and more than 80 percent of human genes associated with disease are known to have a zebrafish counterpart. Additionally, ...

How viruses outsmart their host cells

Viruses depend on host cells for replication, but how does a virus induce its host to transcribe its own genetic information alongside that of the virus, thus producing daughter viruses? For decades, researchers have been ...

Researchers uncover mechanism behind DNA damage control

DNA damage is occurring in our cells all the time due to external agents, such as exposure to sun, or internal agents, like reactive oxygen species. To detect and repair DNA lesions, cells have evolved DNA damage response. ...

RNA polymerase

RNA polymerase (RNAP or RNApol) is an enzyme that produces RNA. In cells, RNAP is needed for constructing RNA chains from DNA genes as templates, a process called transcription. RNA polymerase enzymes are essential to life and are found in all organisms and many viruses. In chemical terms, RNAP is a nucleotidyl transferase that polymerizes ribonucleotides at the 3' end of an RNA transcript.
