rosijanka [135]

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.

I hope this answer helps.
