About how many times does DNA have to fold up to fit in a cell?
Question Date: 2016-02-15
Answer 1:

There is about 6 ft of DNA strands in each of our cells!

The DNA strands don't fold. They curl around little protein beads [histones], creating something like tiny beads on a string. This 'string of beads' in each cell is about 6 inches long.

Then the string of tiny beads coils up into something that looks like a spring [it's called a 30-nm fiber]. Then the spring-like thing folds back and forth into a fatter fiber that forms the arms of the chromosomes.

Folding up the DNA in a cell is like taking a piece of string as long as a football field and coiling it down to a half inch long!

Counting all our cells, with 6 ft of DNA in each cell, all the DNA in my body is long enough to stretch to the sun and back over 300 times! Your body isn't full grown, so maybe you only have enough DNA to stretch to the sun over 200 times.
