Question

which of the following enzymes are part of the replisome during dna replication? select all that apply. telomerase dna polymerase primase helicase

Explanation:

1. Telomerase: Telomerase is involved in the replication of telomeres (ends of chromosomes) but is not part of the replisome, which functions in the main DNA replication fork.
2. DNA polymerase: DNA polymerase is a core enzyme of the replisome, responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.
3. Primase: Primase is part of the replisome. It synthesizes short RNA primers that are necessary for DNA polymerase to start DNA synthesis (since DNA polymerase can only add nucleotides to an existing 3’ - OH group).
4. Helicase: Helicase is a key component of the replisome. It unwinds the double - stranded DNA at the replication fork, creating the single - stranded DNA templates needed for replication.

Answer:

DNA polymerase, primase, helicase
