WebAccurate homologue synapsis during meiosis is essential for faithful chromosome segregation and formation of viable gametes. The finding of Spo11-dependent gamma-H2AX (γH2AX) formation during leptotene and data on mutant mice have led to the notion that synapsis in mammals depends on meiotic DNA double-stranded break (DSB) repair.

WebExplanation: The core histone proteins are H2A, H2B, H3 and H4, over which the DNA is wrapped. Histone H1 is not a part of nucleosome core particle, instead it binds to the linker DNA and thus is referred to as linker histone. Thus, the histone core, linker histone and DNA are the components of the nucleosome.
