Question

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

Explanation:

• RNA Polymerase: Involved in transcription (synthesis of RNA from DNA template), not DNA unwinding for replication.
• RNA Helicase: Acts on RNA, not DNA during replication.
• DNA Polymerase: Involved in adding nucleotides to the growing DNA strand during replication, not unwinding.
• DNA Helicase: Specifically functions to unwind the DNA double - helix at the replication fork during DNA replication.

Answer:

DNA Helicase
