BIO 101 STUDENT EXPLORATION MEIOSIS EXAM WITH COMPLETE SOLUTION 2024 Name: Student Exploration: Meiosis Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary:anaphase, chromosome, crossover, cytokinesis, diploid, DNA, dominant, gamete, genotype, germ cell, haploid, homologous chromosomes, interphase, meiosis, metaphase, mitosis, ovum, phenotype, prophase, recessive, sister chromatid, sperm cell, telophase, zygote Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes? The daughter cells must make a copy of every chromosomes 2. During sexual reproduction, two sex cells fuse to create a fertilized cell with a complete set of chromosomes. What must be true about the number of chromosomes in each sex cell? each must have 23 chromosomes Gizmo Warm-up Meiosisis a type of cell division that results in four daughter cells with half as many chromosomes as the parent cell. These daughter cells mature into gametes, or sex cells. In the MeiosisGizmo, you will learn the steps in meiosis and experiment to produce customized sex cells and offspring. On the STEPS tab, click Male. You are looking at a germ cell, or a cell that will undergo meiosis to become gametes. 1. Read the description of interphaseat the bottom of the Gizmo. What happens to the cell at the beginning of interphase? mRna and protein is synthesized 2. Click on the DNAin the nucleus of the cell. Describe what happens.
