Mitosis Lab Report BioLab3

I. Mitosis in Eukaryotes 1. Describe how cells divide in prokaryotes and eukaryotes. Most prokaryotic cells divide by the process of binary fission. In eukaryotes, cell division occurs in two major steps: mitosis and cytokinesis 2. What are somatic cells? any cell of a living organism other than the reproductive cells. 3. What is the difference between mitosis and cytokinesis? Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm II. Cell Cycle 1. Based on Lab, Exercise 1, draw and label the phases of interphase and mitosis including the major events of each stage as shown. Sign, date and prepare an image of your drawing and include it with this lab report. 2. What percent of the cell life cycle is spent in mitosis? 10-20% 3. During which stage does DNA replication occur? Mitosis III. Chromosome Replication 1. How does the genetic material of sister chromatids compare? During cell division, they are separated from each other, and each daughter cell receives one copy of the chromosome. 2. Describe homologous chromosomes, sister chromatids, and replicated chromosomes. Homologous chromosomes are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location and a A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, 3. Based on Lab, Exercise 3, draw a replicated, homologous pair of chromosomes. Label the sister chromatids and centromeres. Sign, date and prepare an image of your drawing and include it with this lab report. IV. Mitosis and Cytokinesis
