1. What is the primary activity of a cell during the G1 phase of the cell cycle?
Protein synthesis and cell differentiation
DNA replication and cell division
Cell growth and preparation for DNA replication
Chromosome segregation and cytokinesis
2. The cell cycle is highly regulated to ensure that cells can divide correctly.
Cyclins and cyclin-dependent kinases are two protein types that regulate the
cell cycle. Which of the statements below best describes the role of cyclin-
dependent kinases in the cell cycle?
Phosphorylate specific amino acids on other proteins.
Only expressed at specific times during the cell cycle.
Scan for DNA damage during the G1 stage of the cell cycle.
Do not have enzymatic function.
3. If a patient has a deficiency in myeloid precursor cells, which of the following
conditions might they experience?
Enhanced oxygen transport and improved immune function.
Improved muscle regeneration and faster wound healing.
Anemia, increased bleeding, and weakened immune response.
Increased production of lymphocytes and enhanced clotting ability.
4. Describe the significance of the G1 and G2 phases in the cell cycle.
, The G1 and G2 phases are critical for cell growth and preparation
for DNA synthesis and mitosis.
The G1 phase is for DNA replication, while G2 is for cell division.
The G1 phase is for protein synthesis, while G2 is for energy
production.
The G1 phase is when the cell is inactive, and G2 is when it undergoes
apoptosis.
5. Describe the significance of the G1 phase in the context of the entire cell
cycle.
The G1 phase is unimportant as it does not contribute to DNA
replication.
The G1 phase is crucial as it allows the cell to grow and prepare for
the subsequent DNA replication phase, ensuring proper cell
division.
The G1 phase is where the cell undergoes apoptosis.
The G1 phase is primarily focused on the synthesis of RNA.
6. Mitosis is a process of cell division in which one cell goes through a cell
division that results in two daughter cells that are genetically __ _.
different
identical
7. What are the end products of mitosis?
Two daughter cells
One daughter cell
Two parent cells
