Study Notes

Cellular Division Exam - Study Guide

Review session to come
Exam scheduled for
Key terms and definitions will be covered
Cell division - replace damaged cells & lost cells, permits growth & allows for reproduction
M phase - includes 2 overlapping processes: cytokinesis and the nuclear division. Cytokinesis is when the cytoplasm is divided into two daughter nuclei
S phase - synthesis of DNA, also known as DNA replication
Interphase - a cell performs its normal functions, increases in size, and the synthesis of DNA occurs. 90% of the cells life span. only during the cell division are the chromosomes visible. It is cell's normal activity every day.
Interphase - 3 phases(G1, S, G2) G1-first gap where everything is prepared before DNA synthesis, S -synthesis of DNA, G2 - second gap where the cell prepares for division
Sister chromatids - two identical chromatids that make up each chromosome
Prophase - the first stage of both cell division (mitosis and meiosis). longest and most complex stage of mitosis, chromosomes are visible, spindle fibers, centrioles, and asters. Nuclear envelope and nucleoli disappear
Metaphase - chromosomes align on the center of the cell. Spindle fibers coordinate chromosome movement
Anaphase - chromosomes separate at the centromeres, move to opposite sides of the cell.
Telophase - condensed chromosomes and begin to spread into a cluster of chromatin. Nuclear envelope forms, and nucleoli become visible, spindle apparatus and kinetochores disappear.
