NEET BIOLOGY

Detailed explanation-1: -Skin cells reproduce through mitosis. Each new skin cell is an exact replica of its parent cell. Since so many skin cells are lost each day through normal wear and tear, skin cells in the lower level of the epidermis reproduce very rapidly through mitosis to replace those lost cells.

Detailed explanation-2: -The stratum basale, which is a row of columnar cells resting on the basal lamina that separates the epidermis from the dermis. Mitosis occurs exclusively at the basal cell layer and allows for the replacement of cells lost from the surface.

Detailed explanation-3: -During mitosis, the cell shares the copied DNA equally between the 2 new cells. This means that the cell separates all the copied chromosomes into 2 full sets. One at each end of the cell that is splitting in two. The other material that makes up the cell also splits in two.

Detailed explanation-4: -Mitosis creates identical copies of cells. For example, it creates new skin cells to replace dead skin cells. Gametes are the cells needed for reproduction. Unlike other cells, they are not produced through mitosis.
