each one with one new strand and one original strand
each one with two new strands
one with two new strands and the other with two original strands

Why is DNA important?
it is very small and very complicated
it's in everything
it serves as the blueprint for traits of all living things
because we eat it every day for energy
Why does DNA stay in the nucleus?
It cannot move.
It is grounded.
It is lazy.
To protect it from becoming damaged.
How is cancer related to the cell cycle?
There is a problem with checkpoints, causing the cell to divide out of control
There is a problem with Mitosis, making the cell constantly divide.
There is a problem with S phase, causing the cell to continually make new DNA.
There is a problem with G1 phase. The cell keeps growing uncontrollably.
Every time a Gene is expressed, a _________ is made.
Nucleic Acid
Carbohydrate
Protein
fat
What role does DNA play for life?
Provides Nutrients
Encodes (stores and transmits) genetic information
Burned for Short-term energy
Burned for Long-term energy
When cell growth is not controlled, a __________ will form.
Tumor
Organ
Tissue
Organelle
How does cancer spread throughout the body?
Tumors rupture, allowing cells to enter the surrounding tissue and grow new tumors.
Tumors spread like a virus. They destroy cells and little tumors come bursting out to spread throughout the body.
White blood cells move cancer cells through the body.
Tumors never spread. The cells stay where they are growing.
What are the 2 reasons an organism's cells will go through the cell cycle? select all that apply.
Growth of the organism
Healing

Cytokinesis
Mitosis
G1
G2
Which process ensures that the cell is divided into two separate cells?
Cytokinesis
