Cell Cycle Actively dividing up eukaryote flats overtake through a sequence of stages renowned collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) stage, in which the genetic material is duplicated; and an M sta...
DNA. Interphase is also considered a "living" phase of the cell in which the cell receives nutrients, grows, it reads the DNA and carries out other "normal" functions of cells. Most eukaryotic cells spend most of their time in interphase. I...

bone diaphyseal face of the growth plate or physis The growth plate is a disk-shaped structure which is sandwiched between the epiphysis and diaphysis. In the growth plate are two regions, a central and a peripheral. The central region is c...
reproduction: a reproductive system in which two differentiated cells (called gametes) fuse to give rise to a new individual single cell (the zygote) that will be developed by successive mitosis as multicellula. This definition of sexual re...
