Cell Division & Cell Cycle

Cell Division & Cell Cycle. Comparing Mitosis and Meiosis. Cell Division. Cell Division - when a parent cell divides into two daughter cells. All body cells are somatic cells and divide by mitosis Sperm and egg, which are gametes (sex cells) divide by meiosis. Cell Division.

Cell Division and Reproduction

Cell Division and Reproduction. Unit 7. warmup March 13 #. Chromosome DNA is coiled to conserve space in a structure called a chromosome. When the DNA copies to prepare for mitosis, the two copies are each called chromatids and are connected for a while in a doubled chromosome.

Cell Cycle and growth regulation Yasir Waheed

Cell Cycle and growth regulation Yasir Waheed. A cell reproduces by performing an orderly sequence of events in which it duplicates its contents and then divides in two. This cycle of duplication and division is known as the cell cycle. Phases of Cell cycle.
