The Cell Cycle Mitosis: the process by which cells reproduce themselves‚ resulting in daughter cells that contain the same amount of genetic material as the parent cell. Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Cell Division Occurs in a series of stages of phases Interphase occurs before mitosis begins Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils (chromatin) at the start‚ but each chromosome and its copy(sister chromosome) change to sister

Cell Cycle and Mitosis THE CELL CYCLE The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a eukaryotic cell between its formation and the moment it replicates itself. These events can be divided in two main parts: interphase (in between divisions phase grouping G1 phase‚ S phase‚ G2 phase)‚ during which the cell is forming and carries on with its normal metabolic functions; the mitotic phase (M mitosis)‚ during which the cell is replicating itself. Thus‚ cell-division

MITOSIS What is Mitosis? There are various structures within the cell‚ but many are too difficult to see. For example‚ within the nucleus lie the chromosomes. These are important for heredity and reproduction. When a cell splits and becomes two‚ certain processes occur within the nucleus first. One of these processes involves the splitting of the chromosomes. This process is called Mitosis and there are four distinct stages. Mitosis takes place in Regular Body Cells or Somatic Cell. It keeps

Science 9 Chapter 5.1 The Cell Cycle and Mitosis Pg152-158 Notes Cell Replacement and Development -Cells continue to divide as you continue to grow. -Muscle & nerve cells usually do not continue to divide in adult. The Cell Cycle -Life of cell = divided into 3 stages called cell cycle. -Stages = Interphase‚ Mitosis and Cytokinesis -Interphase= cells carry out functions necessary for survival and cells that divide prepare for reproduction. -Mitosis divides duplicated contents of cell’s nucleus

small light bulbs also known as male gametophytes. That week we started the process of fertilization. A group member used distilled water to deposit five drops of water into the petri dish. After sealing it back up we waited several minutes before observing the dish under a microscope. As a result of adding water we observed small black dots moving around rapidly‚ almost “dancing”. From class notes I realized the sperm were seeking out eggs for fertilization. After a while the movement seemed to slow

DNA molecules are produced‚ and a cell replicates it’s chromosomes. In the final stage of interphase‚ G2‚ a cell gets ready to divide and the organelles and molecules needed for cell division are produced. After interphase‚ the cell begins mitosis. The mitosis stage is made up of four smaller phases. The phases‚ in order‚ are prophase‚ metaphase‚ anaphase‚ and telophase. During prophase‚ the chromatin condense into chromosomes‚ the centrioles separate‚ the nuclear envelope breaks down‚ and a spindle
