In molecular biology which of the following histones bind to linker DNA. H1, H2A, H2B, H3.

H1

Explanation:

the histone octamer comprises two copies of core histones H2A, H2B, H3, and H4 [9]. These four core histones consist of an N-terminal tail and a C-terminal histone fold domain.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
