WebMentioning: 14 - Background: A genome-wide wave of histone H3 acetylation and deacetylation occurs during the fungal cell cycle. Results: Cyclin-dependent kinases and the ubiquitin ligase SCF Cdc4 promote timely degradation of Hst3, a sirtuin involved in genome-wide histone H3 deacetylation. Conclusion: Mutations that interfere with cell cycle …
DnaG is a bacterial DNA primase and is encoded by the dnaG gene. The enzyme DnaG, and any other DNA primase, synthesizes short strands of RNA known as oligonucleotides during DNA replication. These oligonucleotides are known as primers because they act as a starting point for DNA synthesis. DnaG catalyzes the synthesis of oligonucleotides that are 10 to 60 nucleotides (the fundamental unit of DNA and RNA) long, however most of the oligonucleotides synthesized are … short and stocky body typeWebprimase.
