Question | Answer |
---|---|
Cell Cycle | a series of events that take place from one cells divison to the next |
interphase | a period of growth and development in eykaryotic cells |
Mitosis | the process in which the neucleus divides to form two identical neucli |
chromosomes | a structure in the neucleus that contains hereditary material |
prophase | Chromatids are visible and the neuclear membraane disentigrates. The centroles move to opposite ends of the cell and spindle fibers are streaching over the cell. |
Metaphase | The pairs of chromatids line up across the center of the cell |
anaphase | cell centrome divides and spindle fibers shorten & move to opposite ends ofthe cell. |
Telophase | The process when the spindle fibers start to dissappear, the chromosomes start to uncoil, and a new neucleus forms. |
Cytokinesis | Divison of the cytoplasm |
Sexual Reproduction | A type of reproduction in which 2 sex cells usually a sperm & egg join to form a zygtote, which will form a new organism |
Asexual reproduction | A type of reproduction in which a new organism is formed. |
Sperm | Male Sex Cell |
Egg | Female Sex Cell |
fertilization | The joining of an egg and sperm |
Zygtote | The cell that forms after fertilization |
Diploid | When cells have pairs of similar chromosomes |
hapliod | When cells don't have pairs of chromosomes ( Sex cells) |
Meiosis | Cell Divison that produces haploid sex cells |
DNA | Deoxyribonucleic acid. Contains genetic material for an organism's growth and function |
gene | A section of DNA on a chromosome |
RNA | Goes to neucleus and gets code from DNA& takes code back to ribmosomes in the cytoplasm |
Mutations | A permanent change in the DNA sequence of a gene or chromosome of a cell |
