Question 3

So considering the answers from the previous 2 questions, what can you speculate about the tightness and denseness of packing that must happen when a naked DNA molecule is wrapped up into a condensed chromosome? Use the measurements from the previous 2 questions to emphasize your point.

QUESTION 2
One average human chromosome consists of a double stranded DNA molecule about 100 Mbp (mega base pairs = million
base pairs) in length.
If that DNA strand were laid out straight (not wrapped up in chromatin), what would be the actual length of that DNA
molecule? Give your answer in millimeters.
The distance from one base pair to the next in DNA is 0.34nm, and one nanometer (nm) is 10-6 millimeters.
34mm
