What is the part of the cell cycle in which DNA is synthesized? What does chromatin remodeling mean? What are the constituents of DNA and RNA? How is RNA formed from DNA? What is a histone Octamer made of? What is the nucleosome is made of?
Like DNA itself, chromosomes are divided into repeating units. In DNA, these are called nucleotides, whereas in chromosomes they are callednucleosomes. A nucleosome is a histone-DNA complex. These were discovered when scientists used caustic materials to dissolve the outer proteins from chromosomes, ...

New experiments using antibodies, green fluorescent protein fusions, and epitope tags show that CENP-A replaces the major histone H3 subunits in a specialized histone octamer and that it does so with histones H4, and probably H2A and H2B. One of the classic hallmarks of chromatin molecular ...
The Polycomb repressive complex 1(PRC1) monoubiquitylates histone H2A at Lys118 (Lys119 in vertebrates). This adds a large (76 amino acid) molecule to the DNA–histone interface. FLP recombinase A site-specific recombinase that is used to engineer specific DNA rearrangements in living organisms...
The histone core octamer of a nucleosome forms hydrogen bonds with what part of the DNA? What is the main post-replicative modification that occurs in DNA? What are 3 parts of a DNA molecule? How are DNA, protein, and carbohydrates involved in the...

a space only one- or two-millionths of a meter wide. Histones exist as octamers, or groups of eight subunits. The DNA winds its way around each histone octamer in the manner of thread wrapping around a spool approximately twice. Under a microscope, this gives chromatin a beady appearance,...
Chromatin in eukaryotic cells is a negatively charged long polymer consisting of DNA, histones, and various associated proteins. With its highly charged and heterogeneous nature, chromatin structure varies greatly depending on various factors (e.g. chemical modifications and protein enrichment) and the ...
