Explain how DNA, which is six feet long, can be stored in the nucleus of a tiny human cell.

Answer 1

Answer:

actually the negatively charged DNA is wrapped to positively charged histone octamer. these all histone combining forms chromatin.

so the long DNA is stored in highly coiled manner

Answer 2

The DNA:

• Every cell in our body has DNA packed into it which is approximately 2 meters long.

• DNA exists in our cell as a double stranded helix.

• The DNA is out cells has a total of 46 chromosomes or 23 pairs of chromosomes.

• This DNA is tightly coiled around what is known as histone proteins.

• These proteins bind the DNA tightly and create a structure called nucleosomes.

• The DNA is a highly coiled structure, like if you twist a piece of fool and keep twisting it you will notice the it shrinks in size, it will accommodate more wool and take up lesser space, the DNA is also twisted just like that in that tiny cell.
