WebEach diploid human cell with 6.4 x 10 9 DNA base pairs has 30 million nucleosomes (3 x 10 7 nucleosomes). It is a known fact that a nucleosome is made up of histone proteins that the DNA wraps itself around. These nucleosomes are then folded repeatedly to form the chromosomes which provide the basic genetic characteristics of humans.

DNA wraps around these histones in chromosomes, so chromosomes are formed in small steps at a time. The structure of the nucleosome resembles a bead strung on a string. However, DNA wraps around the …
WebThe most basic level of DNA condensation is the wrapping of DNA around the histone core proteins. Higher-order packaging is accomplished by specialized proteins that bind and fold the DNA. This generates a series of loops and coils that provide increasingly higher levels of organization and prevent the DNA from becoming tangled and unmanageable. corsicana tx property taxWebDNA wraps around proteins called _____ which help maintain the shape of the chromosomes and keep the DNA coiled.
