Student Name: Access Code (located on the lid of your lab kit): Lab Report Format Expectations Utilize college level grammar and professional formatting when completing this worksheet. Submissions without proper formatting, all required photos or sufficient responses will be rejected. Pre- lab Questions 1. What are chromosomes made of? Chromosomes are made of DNA, histone proteins, and other associated proteins, forming condensed structures within the nucleus of cells. 2. Compare and contrast mitosis and meiosis, ensuring to detail the differences in both function and in process . (Hint : Your response should be 4 -5 sentences long.) Mitosis and meiosis are both processes of cell division, but they serve distinct functions and exhibit fundamental differences in their processes. Mitosis is responsible for the growth, repair, and maintenance of somatic cells, ensuring that each daughter cell receives an identical set of chromosomes to the parent cell. Meiosis, however, is specialized for the production of gametes, involving two rounds of division resulting in four haploid daughter cells with genetic diversity. While mitosis consists of one round of division, meiosis involves two rounds (meiosis I and meiosis II), with unique stages such as crossing over during prophase I and the separation of homologous chromosomes during anaphase I. These differences in function and process are essential for the preservation of chromosome number and genetic stability in somatic cells through mitosis and for generating genetic diversity in gametes through meiosis. 3. Cancer is a disease related to uncontrolled cell division. Investigate two known causes for these rapidly dividing cells and use this knowledge to invent a drug that would inhibit the growth of cancer cells. ( Hint : Your response should be 4 -5 sentences long.) Two known causes of uncontrolled cell division in cancer are mutations in genes that regulate cell growth and division, such as oncogenes and tumor suppressor genes, and abnormalities in signaling pathways that control cell cycle progression. One potential drug to inhibit the growth Lab 3 Mitosis and Meiosis BIO201L of cancer cells could target these abnormal signaling pathways, such as the PI3K/AKT/mTOR pathway or the MAPK pathway, using small molecule inhibitors or monoclonal antibodies to block key proteins involved in promoting cell proliferation. By disrupting these pathways, the drug would interfere with the signals that drive cancer cell growth and division, ultimately slowing down or halting tumor progression. Additionally, targeting specific mutations in oncogenes or tumor suppressor genes with precision medicine approaches, such as gene editing or targeted therapies, could also be effective in inhibiting the growth of cancer cells while minimizing side effects on normal cells.
