Get out the following four assignments for your homework packet -Review Sheet from Monday -Enzyme Letter from Tuesday -Enzyme Worksheet from Tuesday -Cell cycle worksheet from Thursday
If time answer the following question:What are the three main stages of the cell cycle
and what happens in each?
MITOSISThe process a cell uses to copy its
DNA and create two identical daughter cells
Pre-Mitosis: INTERPHASE
This is where the cell spends most of its time
Cell grows, gain nutrients, copies DNA
DNA is “just chillin” in the nucleus
Interphase = In-between
Step 1: PROPHASE
DNA condenses into chromosomes
Chromosomes pair up with their exact copy
Nucleus breaks down
Prophase = Pairs
Step 2: METAPHASE
Chromosomes line up in the middle of the cell
Chromosomes are attached to fibers that stretch from the poles to the middle of the cell
Metaphase = Middle
Step 3: ANAPHASE
The stage when chromosomes separate
Each singular chromosome pulled to opposite sides of the cell by fibers in the cell
Anaphase = Apart
Step 4: TELOPHASE
Cell membrane pinches off to form two cells
Nuclear envelope reforms around DNA
Chromosomes uncondense
Telophase = Two Cells
