Module B Assessment Anchor B.1 Cell Growth and Reproduction I. II. III. IV. Describe the three stages of the cell cycle. a. Interphase i. Gap 1 1. The cell is performing normal duties 2. Cell is growing ii. Synthesis 1. DNA is replicated iii. Gap 2 1. The cell undergoes additional growth 2. Replicates organelles b. Nuclear division i. The DNA is divided ii. Mitosis divides nuclear material once 1. Prophase, metaphase, anaphase, telophase iii. Meiosis divides nuclear material twice 1. Prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, telophase II c. Cytokinesis i. Cytoplasm is divided 1. Animal cells pinch causing a cleavage point 2. Plant cells produce a cell plate (beginnings of a cell wall) Compare the process and outcomes mitotic and meiotic nuclear division a. Mitotic division results in i. Two cells ii. Full number of chromosomes iii. Genetically identical to one another iv. Can be used for asexual reproduction b. Meiotic division results in i. Four cells ii. Half the number of chromosomes iii. Genetically unique iv. Used for sexual reproduction Describe how the process of DNA replication results in the transmission and/or conservation of genetic information. a. DNA replication i. produces identical copies of DNA ii. Uses a semiconservative copy technique iii. Copies are then transferred to new cells through mitosis or meiosis Explain the functional relationship between DNA, genes, alleles, and chromosomes and their roles in inheritance. a. DNA is the universal code of life b. DNA codes for traits in segments called genes (trait: eye color) c. Genes can have varieties called alleles (allele for eye color: brown, blue, or green) d. Chromosomes are structures made of DNA that contain several genes
