Question

multiple - choice question
what did helicase do?
build the dna by adding dna nucleotides
prime the dna molecule by adding rna nucleotides
unzip the dna double helix
glue the dna strands together
rewatch submit

Explanation:

Helicase is an enzyme that plays a crucial role in DNA replication. Its main function is to unwind the DNA double helix by breaking the hydrogen bonds between the base pairs. This separation of the two strands creates a replication fork, which is essential for the subsequent steps of DNA replication.

• "Build the DNA by adding DNA nucleotides" is the function of DNA polymerase.
• "Prime the DNA molecule by adding RNA nucleotides" is the role of primase.
• "Glue the DNA strands together" is done by DNA ligase.

Answer:

Unzip the DNA double helix
