WebGreA is a well-characterized transcriptional factor that acts primarily by rescuing stalled RNA polymerase complexes, but has also been shown to be the major transcriptional fidelity and proofreading factor, while it inhibits DNA break repair. Regulation of greA gene expression itself is still not well understood. So far, it has been shown that its expression is driven by … WebRNA polymerase (the enzyme) splits apart strands of DNA, making an mRNA molecule by adding RNA nucleotides one at a time. These nucleotides are joined together by covalent bonds. Each DNA nucleotide is matched with a complementary RNA nucleotide, with a matching shape and charge distribution.
