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.
C. Genetic variation
Bacteria are very numerous, and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
Answer:
It will die.
