Question

A single histone H1 binds to which of the following? A single histone H1 binds to which of the following? linker DNA on one side of a nucleosome linker DNA on one side of a nucleosome and a second site in the middle of the DNA wrapped around the nucleosome linker DNA on both sides of a nucleosome linker DNA on both sides of a nucleosome DNA and to a region in the middle of the DNA wrapped around the nucleosome

Answer 1

The correct answer is "linker DNA on one side of a nucleosome and a second site in the middle of the DNA wrapped around the nucleosome".

Step-by-step explanation:

Histone H1 is one essential protein that forms the chromatin of eukaryotic cells. The function of histone H1 is to keep in place the DNA that is wrapped around the nucleosome in the chromatin. Since it interacts directly with DNA, histone H1 have DNA recognition sites of 20-80 nucleotides known as linker DNA. A single histone H1 binds to a linker DNA on one side of a nucleosome and a second site in the middle of the DNA wrapped around the nucleosome. These interactions helps to unwrapped the DNA in the nucleosome (see the image for reference).
