The Cell Cycle
What is our mnemonic for the 6 stages of mitosis?
I Prefer Maklouba and Tasty Cane's
What happens in phase G1?
The cell grows
What is chromatin?
Uncoiled, loose DNA
Chromosomes line up at the equator (center) of the cell.
What are the 6 stages of the cell cycle?
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
What happens in phase S?
The chromosomes copy leading to identical pairs of genetic material called sister chromatids.
What are chromosomes?
Tightly wound, condensed DNA
What is another thing that happens during metaphase?
The centromeres are attached to the fibers called spindles which help align the chromosomes.
What are the four stages of mitosis?
Prophase
Metaphase
Anaphase
Telophase
What is the result of the S phase?
We have 92 chromatids instead of 46.
What is a centromere?
Two copies of each chromatid
What happens during Anaphase?
Sister chromatids split from their twins as they're pulled to opposite sides of the cell.
What is the longest phase of the cell cycle?
Interphase
What happens in the G2 phase?
The cell confirms that the DNA has been replicated without error.
What dissolves?
The nuclear membrane
Which is the most dramatic phase of Mitosis?
Anaphase
What are the three phases of Interphase?
G1, S, and G2
What does Interphase lead to?
First stage of mitosis
What happens during prophase?
DNA transitions from chromatin to chromosomes
What are the sister chromatids pulled apart by?
Spindle fibers
