Question

what are number of bands?

Answer 1

Your question is incomplete and figure is not included. Please, be specific on that. If we consider this in terms of solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energies that an electron within the solid may have. In terms of biology, when immature WBCs are first released from the bone marrow into the peripheral blood, they are called as bands or stabs. In addition, if we run a gel (agarose gel or SDS page), the protein or nucleic acids (DNA, RNA) are separated according to their size or charge, and they will be visualized in the patterns of bands. Then we can count the bands.
