1. What is the purpose of the nitrogenous bases found in DNA?
The purpose of nitrogenous bases is to form the structural basis of DNA.
2. What are the TWO ways the cell cycle control system is regulated?
1. Cyclin and Cyclin-dependent Kinases
2. Cellular Signals
3. True or False. If false, make the statement true. In dependent assortment,
traits are not inherited together.
False, in independent assortment, traits are not inherited together.
4. Which phase of the cell cycle is considered a growth phase?
1. G1
2. Cytokinesis
3. S-phase
4. M-phase
5. What is codominance?
When both phenotypes of an allele are visible, such as the red and white
flower, or AB blood type.
6. Which checkpoint in the cell cycle is also known as the spindle checkpoint?
1. M checkpoint
2. G1 checkpoint
3. G2 checkpoint
4. S checkpoint
7. Fill in the Blank: The 5' end of DNA terminates with a
group, while the 3' end terminates with a group.
1. Phosphate, 2. Hydroxyl
8. What is the most common chromosomal abnormality in humans?
Trisomy 21
9. What role does messenger RNA (mRNA) play in the cell?
mRNA is responsible for specifying the amino acid sequences used to build
proteins.
10. True or False. If false, make the statement true. Gametes are known as
diploid because they have sets of chromosomes.
False. Somatic cells are known as diploid because they have sets of
chromosomes.
11. Fill in the Blank: is a protein that fluctuates in concentration at
different phases of the cell cycle, and are specialized enzymes
that phosphorylate other proteins to activate or inactivate them.
1. Cyclin, 2. Kinases (CDKs)
12. Which proteins are packaged with DNA sequences and are necessary for the
replication of DNA?
1. Histones
2. Phospholipids
3. Polymerase
, 4. Histalase
13. What is a growth factor?
The purpose of nitrogenous bases is to form the structural basis of DNA.
