The length of linker DNA varies between species. What is the length of linker DNA if a sample of genomic DNA were partially digested with micrococcal nuclease and the band visualized was 200bp

The length is going to be 200 base pairs.

Explanation:

The nuclease digestion from the micrococcal nuclease is capable of promoting endonuclease activity, which allows cutting only the linker DNA, thus if such digestion were performed then the band visualized presumably would be the linker DNA itself.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
