#Unit 2. Cellular Organization
Histone H3.1 is replicative histone.
#Id: 409
H3.3 is expressed throughout the cell cycle, in contrast to most histones that are expressed during S phase during replication.
#Id: 410
H3.3 is available for assembly at any time in the cell cycle, and is incorporated at sites of active transcription, where nucleosomes become disrupted.
#Id: 411
H3.3 is often referred to as a “replacement” histone.
#Id: 412
The H2A variants are the largest and most diverse family of core histone variants.
#Id: 413
H2AX is normally present in only 10%–15% of the nucleosomes in multicellular eukaryotes
