Dna-directed rna polymerase
WebWhat does "primase" (DNA-directed RNA polymerase) have to do with DNA synthesis? Primase synthesizes a short complementary strand of RNA called a primer that has a free 3' hydroxyl for DNA polymerase to use as a starting point for synthesis of new DNA. WebAnalogous to the DNA-dependent DNA and RNA polymerases described above, RNA-dependent polymerases also utilize single-stranded RNA as a template to synthesize …
