Question

is responsible for unwinding the dna for dna replication. atp synthase primase helicase ligase

Explanation:

• ATP synthase: It is involved in the synthesis of ATP, not DNA unwinding.
• Primase: Synthesizes RNA primers for DNA replication, not unwinding DNA.
• Helicase: Breaks hydrogen bonds between base pairs to unwind the DNA double - helix during replication.
• Ligase: Joins Okazaki fragments on the lagging strand, not unwinding DNA.

Answer:

Helicase
