U2) Mitosis + Cell Cycle 0.0 / 5 ? BiologyCellular processesA2/A-levelAQA Created by: lieselb12Created on: 05-05-20 11:15 What does mitosis produce? 2 genetically identical daughter cells 1 of 12 Why is it important? 4 Growth, cloning, asexual reproduction + repair of damaged cells 2 of 12 What are the 5 parts? Late Interphase, Prophase, Metaphase, Anaphase + Telophase 3 of 12 What is late interphase? DNA has replicated, Nuclear membrane is intact and the nucleolous is visible, Chromosone duplication 4 of 12 What is prophase? chromosones become visible, shorter + thicker, towards the end nuclear membrane disappears 5 of 12 What is metaphase? The spindle fibres attrach to the centrimeres + chromosones align on the cell's center 6 of 12 What is anaphase? spindle fibres contract pulling the sister chromatids apart, chromatids move to opposite ends of the cell, requires ATP 7 of 12 What is Telophase? Nuclear membrane reforms around the chromosones at each pole 8 of 12 What is Cytokinesis -part of telophase? Splitting of cytoplasm to produce 2 genetically identical daughter cells 9 of 12 What are the 4 parts of the cell cycle? G1, S, G2 + mitosis. 10 of 12 What is the interphase part of the cycle? G1 - Cell growth + protein production. / S - synthesis + DNA replication / G2 - Cell prepares for mitosis. 11 of 12 How long is the cell cyclefor a human? 24 hours 12 of 12
