Biology - Cell Cycle and Mitosis Questions and Answers Already Passed what is the cell cycle the sequence of growth and division of a cell what are the 3 general periods a cell goes through during the cell cycle Interphase Mitosis Cytokinesis what are the major events that occur during interphase the cell grows, carries out cellular functions and replicates what is mitosis when the cells nuclear and nucleus material divides where does the cell spend most of its time interphase In which phas...

Mitosis Cell division process which produces two genetically identical daughter cells from a single original parental cell. Genetically controlled process. First: Interphase Followed by: M phase Interphase G1: Active gene expression and cell activity; preparation for DNA synthesis. G0: Terminal differentiation and arrest of cell division. S phase: DNA replication and chromosome replication. There is a single DNA helix per chromatid. DNA replication during S phase results in sister chromatids he...
