WebRNA primer. short piece of RNA needed for DNA polymerase to start. Primase. RNA polymerase that synthesize RNA primers. Dna polymerase III. adding bases to the new DNA chain; proofreading the chain for mistakes. DNA polymerase 1. Removes RNA primer and replaces them with appropriate DNA nucleotides. Web1.) Helicase starts at the origin of replication separating the two strands of DNA, forming two replication forks. 2.) Primase synthesizes RNA primers. 3.) Two molecules of DNA polymerase III (one at each replication fork) build DNA by adding nucleotides onto the primers, extending them.

WebThe basic mechanism of DNA repair. (3 steps) Step 1 (excision): the damage is cut out by one of a series of nucleases, each specialized for a type of DNA damage. Step 2 (resynthesis), the original DNA sequence is restored by a repair DNA polymerase, which fills in the gap created by the excision events. psychology today autism spectrum disorder
