The histones help to package or group DNA molecules in eukaryotic organisms into a structure that we refer to as chromosomes.
The contacts between the DNA and the histones of the nucleosome occurs mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Interspecific competition I believe
Water is a polar molecule because its opposite ends have opposite electric charges.
If think about it if it was asexual then it came from 1 parent so it would be W
