Review ATLAS [Biology] - Module 3: The Cell Cycle

Which describes the Gap 1 Phase?

• The cell undergoes a rapid growth and performs its routine functions.

• DNA Replication occurs during the phase.

• Necessary materials are synthesized for cell division.

• The cell stops dividing and leaves the cycle.

What does the Helicase do during DNA Replication?

• Unzips the DNA strands

• Holds the 2 strands together to prevent them from rejoining

• Reduces supercoiling (relieving tension) and prevents DNA breakage

• Synthesizes a new strand, using the original strand as a template

What does the Single Strand Binding Protein do during DNA Replication?

• Unzips the DNA strands

• Holds the 2 strands together to prevent them from rejoining

• Reduces supercoiling (relieving tension) and prevents DNA breakage

• Synthesizes a new strand, using the original strand as a template

What does the Gyrase do during DNA Replication?
