Question

at which stage of dna replication are the duplex strands separated into a y-shaped replication fork?
a. translation
b. initiation
c. termination
d. elongation

Explanation:

• Translation is the process of synthesizing proteins from mRNA, unrelated to DNA replication strand separation.
• Initiation of DNA replication involves unwinding the double-stranded DNA helix, which creates the Y-shaped replication fork by separating the duplex strands.
• Termination is the final stage where replication is completed, and the replication fork disassembles, not where it forms.
• Elongation is the stage where new DNA strands are synthesized using the separated strands as templates, occurring after the replication fork is already formed.

Answer:

B. Initiation
