Each daughter DNA molecule is composed of...

• one original strand and one new strand

• two new strands

• two original strands

DNA replication must occur before...

• protein synthesis

• cell communication

• apoptosis

• cell division

When does DNA replication take place?

• Whenever new genes are needed

• During the S phase of the cell cycle

• In the middle of mitosis or meiosis

• Immediately before cytokinesis begins

Answer explanation

The DNA must be replicated before cell division takes place so that the daughter cells each receive all the necessary information

Jackson is getting ready for a big presentation at school. In which phase of his preparation does he review all his materials and make final adjustments?

• G1

• S

• G2

• mitosis/cytokinesis

Answer explanation

The G2 phase is when the cell prepares for division by producing proteins and organelles needed for mitosis. It follows the S phase, where DNA is replicated, making G2 crucial for ensuring the cell is ready to divide.

In this phase of the cell cycle, the cell prepares for cell division.

• G1

• S

• G2

• mitosis/cytokinesis
