Mitosis
What stage of mitosis shows a cleavage furrow?
Telophase
The enzyme that ATTACHES complementary strands of DNA during replication is called
DNA polymerase
Proteins that regulate the cell cycle are called
Cyclins
What happens in the S phase so that the M phase can produce 2 daughter cells?
DNA replicates
DNA copies itself in this process
replication

4
Before DNA replicates it MUST:

Equal
Genes contain instructions to build_________.
Proteins
When looking at a graph of number of cells vs time, you would expect to see cancerous cells that divide uncontrollably (because the cell cycle repeats continuously as a result of not entering G0) to have____________ cells than normal cells.

A,T,G,C
Between complementary nucleotides you will find a :
Hydrogen Bond
As a fertilized egg divides, the cells differentiate because...
specific genes are activated

List the phases of mitosis in the proper order
prophase
metaphase
anaphase
telophase
The backbone of DNA is made of:
Deoxyribose and Phosphate
How many codons produce 3 amino acids?
3
Which cells do you think would undergo mitosis more quickly: stomach or liver? Explain why.
Stomach cells divide quicker because the stomach acid destroys them and they need to be replaced.
What cell type is diploid?
Somatic Cells (Body cells)
