Question

question 29
which of the following shows the correct sequence of the cell cycle? (starting with a new cell)
today, we will review the cell
cycle
i require your undivided
attention
a s-phase, g1, g2, mitosis, cytokinesis
b cytokinesis, mitosis, g1, s-phase, g2
c g1, s-phase, g2, mitosis, cytokinesis
d g1, g2, s-phase, cytokinesis, mitosis
question 30
what is occurring in the g1 and g2 phases of a normal cell cycle?
a nuclear division
b growth
c cell division
d chromosome replication

Explanation:

• Question 29: The cell cycle consists of interphase (G1 - cell growth, S - DNA synthesis, G2 - preparation for mitosis) and mitotic phase (mitosis - nuclear division, cytokinesis - cytoplasmic division). So the correct sequence starting with a new cell is G1, S - Phase, G2, Mitosis, Cytokinesis.
• Question 30: In G1 phase, the cell grows in size, makes proteins and organelles. In G2 phase, the cell continues to grow, makes more proteins and organelles, and prepares for mitosis. So growth occurs in G1 and G2 phases.

Answer:

• Question 29: C. G1, S - Phase, G2, Mitosis, Cytokinesis
• Question 30: B. growth
