If DNA has 3,400,000 base pairs, how many turns does it have?
If DNA has 3,400,000 base pairs, how many turns does it have?
Homework Answers
A DNA molecule has an average of 10 base pairs per turn of the helix, hence a DNA consisting of 3,400,000 base pairs will have 3,400,000/10 = 340,000 turns.

1. The genome of organism A consists of approximately 2.184 ×109 base pairs, and DNA synthesis occurs at a rate of 500 base pairs per second. How many minutes would it take to synthesize the entire genome of organism A, if there were only one origin of replication? 2. It turns out that organism A is actually able to synthesize its entire 2.184 ×109 bp genome in only 35 minutes. How many origins of replication must there be? 3. The...
