Cell Cycle (Set 1)

G1, S-Phase, and G2 are all a part of:

• Interphase

• Prophase

• Metaphase

• Cytokinesis

During interphase, DNA is in the form of:

• Chromatin

• Chromosomes

What happens during S-Phase?

• The cell grows

• The cell grows and passes a checkpoint

• The DNA is copied

• The cell splits in two

What is the first phase of mitosis?

• Interphase

• Prophase

Answer explanation

Interphase is the first step of the entire Cell Cycle. Interphase is before mitosis.

Which happens first?

• Chromosomes line up in the middle of the cell

• Chromosomes are pulled apart (as sister chromatids) to opposite sides of the cell.

During which phase does the chromatin condense into chromosomes?

• Prophase

• G2

• Cytokinesis

• Anaphase

Answer explanation

During prophase, the chromatin (long, stringy DNA) condenses into the X-shaped DNA (chromosomes).

What is this (whole thing) called?

• Chromosome

• Centromere

• Chromatin

• Sister chromatid

The arrows are pointing to each

• Chromosome

• Centromere

• Chromatin

• Sister chromatid

Each copy of DNA is held together in the center of the "X" at the ____.

• Cytoplasm

• Chromatin

• Chromatid

• Centromere

During interphase, the DNA is in this form:

• Chromosome

• Chromatin

• Chromatid
