process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be identical to the parent cell‚ since only 1 cell is involved. Meiosis is needed for sexual reproduction‚ while mitosis is needed

The Building Blocks of Life Worksheet Part 1: Mitosis and Meiosis Short-Answer Response Why are the process of mitosis and meiosis both important to a living organism? The process of mitosis and meiosis are both important to a living organism because without them a cell would not be able to reproduce. Mitosis is an asexual process used to replace old and dead cells with new ones by dividing into two identical daughter cells. Meiosis‚ however‚ is the step that makes sexual reproduction possible

Cell cycle checkpoints are control mechanisms in eukaryotic cells which ensure proper division of the cell. The Cell Cycle consists of three checkpoints. These checkpoints are the G1 checkpoint‚ the G2 checkpoint‚ and the M checkpoint. These checkpoints all have different functions. Cells have many different mechanisms to restrict cell division‚ repair DNA damage‚ and prevent the development of cancer. Cancers are formed as cells acquire a series of mutations‚ or changes in DNA‚ that make them divide

A smaller volume allows the DNA to fit in the cell Chromo-somes - Usually
