Dna primase dna replication
Did you know?
DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase. Primase catalyzes the synthesis of a short RNA (or DNA in some living organisms ) segment called a primer complementary to a ssDNA (single-stranded DNA) template. After this elongation, the RNA piece is removed by a 5' to 3' exonuclease and refilled with DNA. WebJun 1, 2024 · Primase: An enzyme that adds a primer (which is a short segment of ribonucleic acid, known as RNA) where DNA polymerase III will attach. DNA polymerase III: An enzyme that creates the new DNA strand by adding nucleotides that are complimentary to the template strand. DNA polymerase I: An enzyme that replaces the RNA primer with …
