PPT-Cell Cycle and Mitosis Chromosomes

Genetic information is passed from one generation to the next on chromosomes Before cell division each chromosome is duplicated or copied C hromosomes Each chromosome consists of two identical . The cell cycle. Mitosis is only one section of the life cycle of a cell. . Interphase is the main part of the cell cycle. This is where DNA is replicated (a copy is made) to prepare for mitosis.. Overview. Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. The Nucleus. The largest most prominent organelle found only in eukaryotic cells. . It . is surrounded by a membrane called the . nuclear envelope . (or nuclear membrane) and contains the . genetic information . A Chromosome and Sister Chromatids. Key Points About Chromosome Structure. A . chromosome consists of DNA that is wrapped around proteins (. histones. ) and condensed. Each . histone. and the DNA wrapped around it make up a . 1. 2 . 4. 8 . How many chromosomes are in the middle cell?. 1. 2 . 4. 8 .

To prepare slides of onion root tips demonstrating the stages of mitosis (somatic cell division) and . identification of cells in the various stages of mitosis.. The . cell cycle. is a repeated pattern of growth and division that occurs in eukaryotic cells. . This cycle consists of three phases: G1, S, G2. The first phase represents cell growth while the last two phases represent cell division.. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. Interphase. Mitosis. Prophase. Metaphase. Anaphase. Telophase. Cytokinesis. Interphase. Longest phase of the cell cycle. Cell grows to mature size. Replicates DNA. Prepares for division. Mitosis. Mitosis is the process of cell . General Biology. Name. ________KEY_______________________. Reproduction. All Cells come from other cells (. Remember the cell theory?. ). Asexual – Organisms formed by only one parent; offspring are identical; fast; fine for environments that don’t change frequently since each organism is a clone. Chromatin. - unwound DNA (loose). . Copied. Sister chromatids. - two identical copies of DNA (loose). . Coiled and Connected. Chromosomes. - two coiled, identical copies of DNA connected to each other (tight). Question #1. Looking at the diagram below, what would be the correct order of the illustrated stages of mitosis?. B-D-C-A. A-B-C-D. A-B-D-C. B-C-D-A. Question #2. The diagram below illustrates the stages of the cell cycle. Inhibitors stop the cycle at G1 to avoid cells dividing out of control. When mutations take place and do not allow the inhibitors to stop the cell cycle, what can happen in the body?.
