Question

How many base pairs of DNA helix are there in a typical nucleosome?

Answer 1

Number of base pairs in Nucleosome:

1. As it relates to genomics, the phrase "double helix" is used to define the actual makeup of DNA.
2. Two connected strands that spiral around one another to resemble a twisted ladder in a helix-like structure make up a DNA molecule.
3. A nucleosome is a segment of DNA that is encircled by a protein core.
4. DNA can be compressed into a smaller volume within the nucleus by forming a combination with proteins known as chromatin.
5. The structure of the expanded chromatin resembles beads on a string when examined under a microscope.
6. The length of a DNA is measured in terms of base pairs, that is number of nucleotides present.
7. A nucleosome is fundamental structural unit of Eukaryotic chromosome.
8. It consist of histone proteins connected to each other by coiled DNA.
9. A nucleosome double stranded DNA helix can be 200 bp long.
