In bacteria, primase binds to the DNA helicase forming a complex called the primosome. Primase is activated by the helicase where it then synthesizes a short RNA primer approximately 11 ±1 nucleotides long, to which new nucleotides can be added by DNA polymerase. Archaeal and eukaryote primases are heterodimeric proteins with one large regulatory and one minuscule catalyti… WebOct 28, 2024 · Primase is an enzyme that synthesizes short RNA sequences known as primers. The primers that are synthesized are complementary to a single-stranded piece of DNA and serve as its template. It is crucial for primase to synthesize primers before DNA replication can occur.
