Answer #1

The correct option is 5. all of them are true.

Nucleosome contains 147 nucleotides, H2A and H2B. In nuclosome, histone protein core is surrounded by DNA. The nucleosome core particle consists of approximately 147 base pairs of DNA wrapped in left handed superhelical turnsaround a histone octamer consisting of two copies of H2A, H2B, H3, and H4. Core particles are connected by stretches of linker DNA.

    Abstract #1 Histone H3 phosphorylation near the nucleosome dyad alters chromatin structure. Nucleosomes contain ∼146 bp of DNA wrapped around a histone protein octamer that controls DNA accessibility to transcription and repair complexes. Posttranslational modification (PTM) of histone proteins regulates nucleosome function. To date, only modest changes in nucleosome structure have been directly attributed to histone PTMs. Histone residue H3(T118) is located near the nucleosome dyad and can be phosphorylated. This PTM destabilizes nucleosomes and is implicated in the regulation...
