1
Mitosis Why divide? -Reproduction -Growth -Repair
2
Two Types of Reproduction
Asexual Sexual What are the advantages and disadvantages of sexual vs. asexual reproduction?
3
Process of Cell Division
Genetic material? Chromosomes Prokaryotes Eukaryotes
5
DNA Vocab Several versions
Chromatin- DNA and proteins during interphase Chromosomes Tightly coiled DNA that condense prior to division Chromatid
6
Cell Division Why condense the chromatin into chromosomes?
Eukaryotic vs. Prokaryotic Prokaryotic: Binary fission
7
Cell Cycle Interphase Mitotic phase G1 S G2
Very tightly controlled. Why?
8
Mitosis Non-reductive Identical daughter cells PMAT
9
Prophase Nuclear envelope breaks down
Chromatin condenses into chromosomes
10
Metaphase Chromosomes line up in the middle of the cell
11
Anaphase Sister chromatids split apart and go to opposite ends of the cell Chromosomal amount is doubled temporarily
12
Telophase Sister chromatids move further apart
Nuclear envelopes surround each set Chromosomes decondense back into chromatin Cytokinesis occurs
13
Cytokinesis Division of the cytoplasm
