Cell cycle
DNA and RNA
Mitosis
100
Most cells spend most of their time in this phase of the cell cycle.
What is interphase? (Everything except mitosis)
100
This is the type of molecule DNA and RNA are.
What are nucleic acids?
100
As body cells, when would mitosis occur?.
What is growth and repair?
200
In this phase of the cell cycle, DNA is replicated.
What is synthesis / S?
200
This is the base-pairing rule for DNA and RNA (which letters go with which?)
DNA: A-T, C-G
RNA: A-U, C-G
200
This is the goal of mitosis.
What is creating two identical copies of a body cell?
300
These are the four stages of the cell cycle (full names - say what the letters stand for)
G1 - Gap one
S - Synthesis (DNA recplicated)
G2 - Gap two
M - Mitosis
300
List two similarities and two differences between DNA and RNA.
DNA only: Has Thymine (T), is double-stranded, is found in the nucleus of the cell
RNA only: Has Uracil (U), is single-stranded, is found in ribosomes, cytoplasm, nucleus, and elsewhere
Both: Nucleic acids, have a sugar-phosphate backbone, have four bases, have A, C, and G
300
These are all the phases of mitosis.
Prophase
Metaphase
Anaphase
Telophase
400
These are places in the cell cycle where the cell ensures it is healthy and normal.
What are checkpoints?
400
Explain the basic process of DNA replication. Can use drawings!
400
Explain the relationship between mitosis and cancer.
Cancerous diseases are a result of mitosis happening too often and leading to uncontrolled growth of cells. This is usually due to one or more checkpoints at each part of the cell cycle failing to do its job and stop the cell cycle.
500
what cells -like brain cells -will enter when they complete the cell cycle
G0
500
Draw a DNA molecule and label a nitrogenous base, a base pair, a sugar, a phosphate, and a hydrogen bond.
500
Draw all the phases of mitosis.
