There are five major types of histones in eukaryotic cells. One of these is not part of the nucleosome core but is thought to participate in locking the two turns of DNA into place. Which histone is this? H3 H2A H4 H1 H2B
Added by Mark S.
Step 1
There are five major types of histones: H1, H2A, H2B, H3, and H4. The nucleosome core is composed of an octamer of histones, which includes two copies each of H2A, H2B, H3, and H4. The histone that is not part of the nucleosome core but is thought to participate Show more…

Which of the following best describes the features of histones? a) H1 is the most crucial histone protein in the nucleosome core particle. b) In order to compact the DNA enough for eukaryotic chromosomes to fit into the nucleus, thousands of base pairs of DNA often wrap around each nucleosome core particle more than a dozen times. c) Among eukaryotes, the amino acid sequences of histone proteins are highly diverse. d) Along a 10,000 bp segment of DNA, you expect to find twice as many histone protein H4 as histone protein H1. e) The 5 types of histone proteins in chromatin are acidic proteins with a negative charge that assists them with binding to DNA.
With which of the following structures does histone H1 primarily associate? Group of answer choices H3/H4 tetramer the histone octamer linker DNA H2A/H2B tetramer nucleosome core particle Which of the following is NOT a result of histone acetyltransferase (HAT) activity? Group of answer choices remodels chromatin fibers condenses chromatin increases gene activity neutralizes the positive charge of histones adds acetyl groups to histones
