Answer:
<h2>5 minutes
</h2>
Explanation:
1. In bidirectional replication; there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.
2. So, by the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize 500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.
I've looked us up ever since you posted it the only thing I can come up with is letter A because it talks a lot about Mountain chains that talks a lot about the ocean floor and the Hawaiian stuff so try a
B. Mutations cause a person's body cells to divide uncontrollably. There isn't a signal for cells to stop dividing, so this can cause cancer because cancer cells won't stop dividing without this signal.
TRUE, with also sharp points
