Function of primase during dna replication

WebCreated by. Oneika_Smith Teacher. DNA REPLICATION: Before the lagging-strand DNA exits the replication factory, its RNA primers must be removed and the Okazaki fragments must be joined together to create a continuous DNA strand. The first step is the removal of the RNA primer. RNAse H, which recognizes RNA-DNA hybrid helices, degrades the … WebThe primase however is a typical RNA polymerase, capable of initiating polynucleotide synthesis de novo by positioning a complementary ribonucleoside 5'-triphosphate …
