WebDouble-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of “beads on a string.”. The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the chromosomes condense even further. DNA replicates in the S phase of interphase. After replication, the chromosomes are … WebThe nucleosome consists of about 200 bp wrapped around a histone octamer that contains two copies of histone proteins H2A, H2B, H3 and H4. ... The DNA that is between each histone octamer is called the linker DNA and can vary in length from 8 to 114 base pairs. This variation is species specific, but variation in linker DNA length has also been ...
