Term | Definition |
cell cycle | the process by which cell division occurs |
chromatin | loose DNA and proteins in nucleus |
chromosomes | tightly wound up DNA and proteins |
sister chromatids | 2 identical halves |
centromere | connects 2 sister crhomatids |
interphase | cell is growing/copying DNA getting ready to divide |
G1 | Growth and development of cell |
synthesis phase | DNA must be copied before you make new cells |
G2 | Prepares for cell division |
mitosis | nucleus divides |
prophase | the nuclear envelope breaks apart and chromatin condenses into chromosomes |
metaphase | Chromosomes line up across the middle of the cell |
anaphase | each identical sister chromatid is split apart, individual chromosomes start to move to opposite sides of the cell |
telophase | Each side of the cell has a copy of the chromosomes, the nuclear envelope ref ors and the spin dal fibers disappear. Chromosome uncoil back into chromatin |
nuclear envelope | |
spindle fibers | connect to the center of each chromosome at the centromere |
centrioles | They help to organize spindle fibers |
animal cell cytokinesis | cell membrane moves inward until the cell is pinched into two |
plant cell cytokinesis | cell plate forms midway between the divided nuclei developed into cell wall |
daughter cells | two identical cells with the same DNA split into two |
cancer | is a disease with uncontrolled cell growth |
factors that influence cancer | Heredity
Environment
