Mytosis |
A type of cell division. *Growth and development of an organism. |
|
|
1. Parent cell contains _________ chromosomes. 2. Also known as _____________. |
1. 46 2. Diploid (2N) * Daughter cell also contains 46 chromosomes. 23 from each parent. |
|
|
1. Mothers egg and father's sperm each contains __________ chromosomes. 2. Also known as _____________. |
1. 23 2. Haploid (1N) |
|
|
Two Parts of the Cell Cycle |
1. Interphase 2. Mitosis |
|
|
Interphase: Prep for cell division |
G1 - Growth & Increase in size of cells. Protein Synthesis. S - DNA Replication "doubling" G2 - Growth & Prep for Mitosis. ATP Synthesis. Duplication of organelles. |
|
|
Mitosis: Sharing of DNA (chromosomes) & sharing of organelles. |
Prophase Metaphase Anaphase Telophase |
|
|
Prophase |
Chromosome condense and become visible. Formation of spindle fiber. |
|
|
Metaphase |
Chromosomes align themselves in a plane at center of spindle. |
|
|
Anaphase |
Sister chromatids split/seperate and travel/migrate toward opposite ends (poles). |
|
|
Telaphase |
Chromosomes arrive at the ends of spindle and begins to disassemble Cytokinesis or cell division of cytoplasm (sharing of organelles). |
|
|
Karyotype |
Systemic arrangements of chromosomes in 23 pairs. #1-#22 Known as Autosomes - made up of Homologues. #23 Sex Chromosome (xy or xx) |
|
|
Organization of Genetic Material (DNA) |
Chromosome > Chromated > Chromatis > Nucleosome > 1. Histone 2. DNA DNA> Nucleotides > Building blocks of DNA Nucleotides > Phosphate + Sugar + Base |
|
|
DNA Bases |
A - Adenine C - Cytosine G - Guanine T - Thymine |
