WebDNA nucleotide repairing. [7] (NER)TF II H is a general transcription factor that acts to recruit RNA Pol II to the promoters of genes. It functions as a helicase that unwinds DNA. It also unwinds DNA after a DNA lesion has been recognized by either the global genome repair (GGR) pathway or the transcription-coupled repair (TCR) pathway of NER. WebThe helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by ...
