Which of the following are features of nucleosomes? A nucleosome contains approximately 20 base pairs of DNA. The DNA in a nucleosome is wound around eight histone proteins. Between nucleosomes is a stretch of DNA called "linker DNA". A nucleosome contains 8 different types of histones. In a nucleosome, DNA is wrapped 4 times around the histone core. H1 seals off where DNA enters and leaves the nucleosome. Nucleosomes contribute to DNA packing. Nucleosomes in chromatin are arranged in straight, side-by-side chains. Nucleosomes are about 10000 Angstroms in diameter. Histones have tails that stick out and can be modified, affecting DNA expression.
