Question

Which statement is false?

a) When DNA is being replicated inside a cell, local heating occurs, allowing the two strands to separate.
b) Prokaryotic cells have a single DNA replication origin in their chromosomes.
c) Meselson and Stahl’s experiments ruled out the dispersive model for DNA replication.
d) DNA replication is a bidirectional process that is initiated at multiple locations along chromosomes in eukaryotic cells.

Answer 1

Answer:

The correct answer is option A.

Explanation:

The separation of the two strands is not necessary for the replication process to occur. The initiation of the replication process is accomplished by the association with the origin of replication with the initiator proteins.

Prokaryotic cells consist only one DNA replication origin where is in the eukaryotic cells the replication is bidirectional and begins at multiple locations.

Thus, the correct answer is the option A)
