what complex is responsible for unwinding the dna double helix for replication?
rna helicase
rna polymerase
dna polymerase
dna helicase

Explanation:

Question 5

Semiconservative DNA replication means each new DNA molecule has one old strand and one new strand, not old - old and new - new.

DNA helicase unwinds the DNA double helix during replication. RNA helicase acts on RNA, RNA polymerase synthesizes RNA from DNA template, and DNA polymerase synthesizes DNA strands.

Answer:

B. False
