Cell Replication Jeopardy Cell Cycle 100- In which phase of the cell cycle does the cell division take place? M 200- What are the 4 phases of the cell cycle? G1, S, G2 and M 300- What is the name for the time period in between cell divisions? Interphase 400- In which phase of the cell cycle is the DNA replicated? S phase 500- In eukaryotes what are the 2 steps of cell division? Mitosis and cytokinesis Mitosis 100- In mitosis one diploid cell becomes how many new daughter cells? 2 diploid cells 200- What are the 4 phases of mitosis in order? PMAT 300- What is the job of the spindle fibers? Separates the sister chromatids during division 400- During which phase of mitosis do the sister chromatids line up along the center of the cell and the spindle fibers attach to the centromere? Metaphase 500- Why is cytokinesis not considered part of mitosis? Mitosis is division of the nucleus only and cytokinesis is division of the cytoplasm Meisosis 100- In what type of cells does meiosis occur? Gametes or sex cells 200- How many cell divisions take place during meiosis? 2 divisions 300- What is it called when 2 homologous chromosomes combine together during prophase 1 of meiosis? Tetrads 400- Why is crossing over so important to the survival of a species? Provides variation in the offspring 500- Give 3 differences between mitosis and meiosis 2 divisions, gametes vs somatic cells, number of cells formed, variation, crossing over Cell Cycle Regulation 100- What will form if cell cycle regulators do not function properly? Cancer cells 200- What is the name of the main protein which regulates the cell cycle? Cyclin 300- What are the 2 types of tumors that can form? Benign and malignant 400- Give 2 types of cancer treatments Surgery, radiation and chemotherapy 500- What is it called when a cancer cell migrates to a different part of the body? Metastasize Grab Bag 100- What is the DNA called when it is not dividing? Chromatin 200- In a human how many chromosomes are in a haploid cell? 23 300- What is the part of the chromosome called where the 2 sister chromatids connect to each other? Centromere 400- What is a karyotype used for? To diagnose genetic abnormalities 500- What forms in plant cells during mitosis that does not exist in animal cells? Cell Plate
