WebThe double-stranded DNA template strand is unzipped and unwound by a DNA helicase. The strands are kept apart by the single-stranded binding proteins (SSBs), which also stop them from re-annealing. A short RNA primer is created by the RNA primase as a starting point for DNA polymerase to initiate replication. WebDNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. ross beames

WebTranscription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). WebDNA replication steps. 1) Helicase- unwinds the parental double helix. 2) DNA topoisomerase - upstream of helices alleviating torsional strain. 3) Single-strand binding proteins (SSBP) stabilize unwound DNA, aided by DNA gyrase (topoisomerase). 4) Primase synthesizes a short RNA primer for DNA polymerase to bind to in the 5' to 3' …
