Cell Life Cycle
Two major periods:1. Interphase: cell grows and undergoes usual
activities2. Cell division: cell reproduces asexually
Prepare: DNA Replication
DNA helix uncoils and separates into 2 nucleotide chains
Each chain acts as a template for building a new nucleotide strand
Complementary pairing of nucleotide bases
Interphase:
Cell is just living
Growing and normal metabolic processes
At the END of interphase: replication of chromosomes
Replication of centriole (centrosome)
Prophase:
Centrioles separate and begin to move to opposite sides
Nuclear envelope breaks apart
Mitotic spindle forms (microtubules)
Cytokinesis
At the very end of telophase
Formation of cleavage furrow (microfilaments)
Both cells back to interphase
Cell Division Packet
Groups of 4 or 5
Each group member must draw out and label assigned event of cell division (IPMAT)
Staple the sheets in order
Write your name on your specific sheet
