Problem: Which ofthe following is required for chromatin to condense into the 30nm fiber?A. histone H1B. chromosomal scaffolding proteinsC. histone tails extending from the nucleosomeD. histone H1 & histone tails extending from the nucleosome.

FREE Expert Solution

In eukaryotes, DNA is packaged into relatively condensed structures known as chromosomes. In this packaging the DNA are wrapped around histone proteins to form nucleosomes, with a 10-nm diameter. These nucleosomes are then packaged further into 30-nm diameter structres and looped domains before finally forming the chromosome structure.
