PDF-Cell Cycle

1 Cell Cycle is an orderly sequence of events by which a growing cell duplicates its contents and divides into two The period required to complete one cell cycle is called generation time eg 20. Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. 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 . Just like people have phases of development,. Cells have phases too.. In somatic (body) cells, a parent cell produces 2 daughter cells.. The purpose of mitosis is for growth and repair of tissue.. Three Phases or Stages. Unicellular organism- cell division reproduces . an entire . organism. Multicellular. organisms- cell . division . can . produce . growth or progeny.

How many phases are in the cell cycle as shown in the diagram in Model 1?. Four.. 2. Starting at the starred cell, what is the order of the stages of a cell’s life?. G1, S, G2, M.. 3. During which phase does the size of the cell increase?. Phases of the cell cycle. Interphase. Mitotic Phase. Interphase. G1. - a cell grows and develops. S. - a cell continues to grow but copies its DNA. G2. - still growing but begins to store energy and get ready to divide. . 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. The cell cycle, or cell-division cycle, is the series of events that takes place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed . 7/22/2009 Cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes. As you grow from an infant to an adult, you pass 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 .
