DNA Cell Cycle

What is the significance of C in the diagram?

• This is where DNA is replicated or doubled.

• This is where the cell grows in size.

• This is where the cell prepares to divide.

• This is where the cell actually splits into 2 identical cells.

Answer explanation

C = S Phase which is where DNA is doubled/replicated.

What is the significance of I in the diagram?

• This is where DNA is replicated or doubled.

• This is where the cell grows in size.

• This is where the cell prepares to divide.

• This is where the cell actually splits into 2 identical cells.

Answer explanation

I = Mitosis which is where the cell prepares to split and goes through prophase, metaphase, anaphase, and telophase.

What is the significance of J in the diagram?

• This is where DNA is replicated or doubled.

• This is where the cell grows in size.

• This is where the cell prepares to divide.

• This is where the cell actually splits into 2 identical cells.

Answer explanation

J = Cytokinesis which is when the cell actually divides into 2 identical somatic cells.

Which of the following is the first step in the DNA Replication process?

• DNA Polymerase attaches complementary nucleotides to the template strand.

• Helicase unzips the DNA strand at the hydrogen bond.

• Ligase glues the 2 strands together and 2 IDENTICAL double helix strands are made.

What phase do cancer cells NOT enter?

• Mitosis

• G0

• G1

• S Phase

What phase of mitosis is pictured?

• Prophase

• Metaphase

• Anaphase

• Telophase

Answer explanation

Metaphase = Middle

Chromosomes are aligned in the middle of the cell

What phase of mitosis is pictured?

• Prophase

• Metaphase

• Anaphase

• Telophase

Answer explanation

Anaphase - away/part

Chromosomes are being pulled AWAY/APART from each other to opposite sides of the cell.
