WebCell Cycle and Meiosis Review Name the phases in Mitosis and explain what happens to the DNA in each phase. It starts with interphase. This is where the cell is performing its normal functions. Then there is prophase when the nuclear envelope dissolves and the cell prepares for separation. Then there is where the spindle fiber connects to a … WebFigure 1.3. 2: The cell cycle consists of interphase and the mitotic phase. During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei.

WebIn eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when … Webb) Sister chromatids are only formed during mitosis. Homologous chromosomes are formed during meiosis. c) Homologous chromosomes are identical copies of each other. One sister chromatid comes from the father, and one comes from the mother. d) Homologous chromosomes are closely associated with each other in both mitosis and …

WebOne of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into four cells that have half the number of chromosomes. WebCorresponding Author.
