Name __________________________________________ Period _____ Date __________ Mitosis Book Work! CHECK SHEET ASSIGNMENT Read pages 138-142 in your text book to help you answer these questions! Define the following vocabulary: Chromosome: ______________________________________________________________________________________ Histone: ___________________________________________________________________________________________ Chromatin: ____ ___________________________________________________________________________________ Chromatid: ________________________________________________________________________________________ Centromere: _______________________________________________________________________________________ Telomere: ________________________________________________________________________________________ Prophase: _________________________________________________________________________________________ Metaphase: ________________________________________________________________________________________ Anaphase: _________________________________________________________________________________________ Telophase: ________________________________________________________________________________________ Answer the following questions: 1. Draw what a chromosome looks like during metaphase. Identify the chromatids and the centromere. 2. Briefly explain why the daughter cells resulting from mitosis are genetically identical to each other and to the original cell. 3. How do prophase and telophase differ? 4. Using a light microscope, you observe a cell that has no nucleus. What features would you look for to determine whether it is a eukaryotic cell undergoing mitosis or a prokaryotic cell? 5. For a cell to make proteins, enzymes must access its genes. When histones are modified with acetyl groups, their positive charge is neutralized, so they wrap DNA less tightly. How might this affect the rate of protein synthesis?
