Be sure to turn in any labs from yesterday. . . Today . we will be discussing:. Mitosis. Every minute your body needs to make 300 MILLION new cells!!. Your DNA carries all the instructions for the cell, including when to do mitosis. Notebook Page 12. Warm . Up & Spiral. 2/23/2017. What is the chemical formula for glucose? . How many hydrogen atoms are in glucose? . What is protein synthesis? . OBJECTIVES: 8.L.5.1. -TSWU that cells carry on the many functions needed to support life including cell respiration, photosynthesis, protein synthesis, mitosis, and meiosis. . 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 . When Making New Cells . Goes Terribly . Wrong. Regulating the cell cycle. Not all cells move through the cell cycle . at the same rate. :. Most Muscle cells and nerve cells do not divide at all once they have developed. Edited By: Ashlee Palermo. Objectives. Define mitosis.. Define meiosis..

Figure 19.0 Chromatin in a developing salamander ovum. Chromatin – the less tightly coiled DNA-protein complex. Centromere – the region of the chromosome that holds the two sister chromatids together during mitosis.. SEX CHROMOSOMES & AUTOSOMES. Sex chromosomes are chromosomes that determine the sex of an organism, and they may also carry genes for other characteristics. . KEY CONCEPT . Cells divide during mitosis and cytokinesis.. Show biology presentation film . clip mitosis 2. Chromosomes condense . at . the start of mitosis.. DNA wraps around proteins (histones) that condense it.. 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.. Genetic information is passed from one generation to the next on . chromosomes. .. Before cell division, each chromosome is duplicated, or copied.. C. hromosomes.
