EQ:. What is the importance of meiosis in providing genetic variation?. . SPECIALIZED CELLS. You have many specialized cells in your body that can be divided into two groups. . 1. . . SOMATIC. = body cells; make up most of your . 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 . diploid. Sex cells (gametes/germ cells) have only one set of chromosomes . . = . haploid. . That means when fertilization . occurs, the new individual will. have the correct number of chromosomes.. Means “to move the cell”. Approximately 5% of cell’s life. Process differs in . Heterotrophs. (Animals) . Autotrophs. (Plants) due to presence of cell wall. HETEROTROPHS. AUTOTROPHS. Cell. membrane . Unicellular organism- cell division reproduces . an entire . organism. Multicellular. organisms- cell . division . can . produce . growth or progeny. Cell . division functions in reproduction, growth, and repair. Topic 1: DNA Organization. By the end of this topic, you should be able to…. Identify parts of a chromosome. Explain why DNA has to copy and coil before cell division. Explain why cells cannot continue to grow forever. 1. Cell Division. The ability of organisms to produce more of their own kind is the one characteristic that best . distinguishes living . things . from nonliving . matter.. Cell division . functions in . CELL CYCLE. . The . sequence of events by which a cell duplicates its genome, synthesis the other constituents of the cell and eventually divides into two daughter cells. .. Phases of cell cycle :. •Interphase :. 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.. 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, e.g., 20 : is the changes which occur in the cell during its division (mitosis) and during its rest (interphase).. OR . sequence of phases in the life cycle of the cell. 3- . 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 . 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 .
