Answer:
The protons and the neutrons are found in the nucleus of an atom.
Explanation:
Atoms are best described as the smallest unit of any matter.
Protons can be described as part of an atom which carries a positive charge. The protons are enclosed in the nucleus of the atom.
The neutron is the part of the atom that carries zero charge. The neutron is also enclosed in the nucleus of the atom.
The electrons can be described as the part of an atom that carries a negative charge. The electrons move around the nucleus in orbits.
Nucleosomes are composed of "histones" class of molecules.
<u>Explanation:</u>
Histones usually presented in eukaryotic nuclei of cells which seemed as strong level of proteins that bundle and organize DNA into structural groups called nucleosomes in biological science.
They are chromatin's chief protein elements, functioning as spools along which DNA spins, and playing a major role in regulating genes. Five forms of histones have been recognized:
- H1 (or H5), H2A, H2B, H3, and H4;
- H2A, H2B, H3, and H4 are the main histones and H1 and H5 are the linker histones.
