Honors Biology Study Guide: Cell Cycle, Regulation, and Differentiation

Cell Growth Limitations Surface area: Volume Asexual vs Sexual Reproduction Prokaryotic vs. Eukaryotic Cell Cycle Binary Fission vs Interphase and Mitotic Phase DNA, Chromosomes, Chromatin, Chromatids, Nucleosomes, Histones, Centromeres, Spindle, Centrioles, Parent/ Daughter cells Know the following phases, what is occurring during them, the order, what cell contents appear like during the phase, etc: Interphase G1 S G2 Mitotic Phase Mitosis Prophase Metaphase Anaphase Telophase Cytokinesis Animal Cell vs Plant Cell

Chemical control Cancer Checkpoints Cyclins Proteins Internal vs External Control Cancer Definition, Cause/Why? Stages (T, N, M) Proper treatments for each stage –> surgery, chemotherapy, radiation Malignant vs. Benign

Differentiation Stem Cells Definition Levels of organization ( cells  tissue  organ  organ systems  organism) How does differentiation happen if all cells have same DNA Why was the roundworm chosen as a good specimen to examine for differentiation? Stem Cells Two possible fates Embryonic vs adult Totipotent, pluripotent, and multipotent Pros/cons: Which is better for lab use? Which has ethical debates surrounding it? Which one has greater potential to become more things? 3 important uses of stem cells in scientific research Specific regenerative therapies (transplant organs, spinal cord injury, etc) Plant stem cells Location Capacity Technological possibilities for stem cells
