Answer:
The answer is 6.8 meters.
Explanation:
During the S phase of the cell replication, the DNA is doubled before the division of the cell which means that it is twice it's original length.
At 0.34 nanometers, 3 billion base pairs (3.000.000.000) comes up to 3.4 meters and during the S phase the length is doubled so it is 6.8 meters long.
