Question

What is primase in DNA replication?

Answer 1

DNA primases

1. At the DNA replication fork, DNA primases are enzymes that must be active all of the time.
2. They catalyze the creation of small RNA molecules that are employed as DNA polymerase primers.
3. Primers, which are four to fifteen nucleotides long, are made from ribonucleoside triphosphates.

Role of DNA primases in DNA replication

1. Primase works by forming short RNA sequences that are complementary to a single-stranded DNA template.
2. Before DNA replication takes place, primers must be produced by primase.
