Eukaryotic cells have 14 dna polymerases
WebIn vitro studies have shown that prokaryotic DNA polymerases can use mRNA as a primer when the replication fork collides with the RNA polymerase , and this is also the case for eukaryotic cells. Stuckey et al. [ 125 ] found that in S. cerevisiae, RNA polymerase I transcription constraints led to persistent R-loops in the ribosomal DNA locus. WebJan 11, 2024 · Origin DNA melting is an essential process in the various domains of life. The replication fork helicase unwinds DNA ahead of the replication fork, providing single-stranded DNA templates for the replicative polymerases. The replication fork helicase is a ring shaped-assembly that unwinds DNA by a steric exclusion mechanism in most DNA …
