Cell Cycle
What is happening at S-Phase?
During this stage the cell is making copies of its DNA
What happens at prophase?
During this phase of mitosis the cell’s DNA turns into chromosomes and the nucleus begins to dissolve
A molecule that holds your genetic instructions
DNA
DeoxyriboNucleic Acid
What 3 stages are part of Interphase?
Growth 1, Synthesis, and Growth 2
What is happening at Anaphase?
During this phase of mitosis sister chromatids are pulled apart by spindle fibers
What happens during Mitosis?
During this stage the cell separates its DNA into two new daughter cells
What happens at G1?
During this stage the cell is growing and getting ready to make a copy of its DNA
What is happening at telophase?
During this phase of mitosis the cell forms two nuclei around the separated sister chromatids
Name one reason your body needs new identical cells.
So you don't have liver cells where your skin cells should be.
If the cells were not identical then their jobs would be different. Each type of cell has a specific job.
Why would it help for chromosomes to become visible?
By compacting the DNA it is easier to move without getting tangled.
What happens at metaphase?
During this phase of mitosis the cell’s DNA gets moved toward the center of the cell by spindle fibers
What are Chromosomes?
Tightly packed bundles of DNA that carry genetic information
What is happening at G2
During this stage the cell continues to grow and makes sure it is ready for cell division.
What might happen to the daughter cells if we didn't make copies of their DNA before dividing?
What is a benefit for having metaphase?
Allows for better organization and even separation of DNA during mitosis.
