Multiple Choice

Why is DNA replication necessary for cells?

• To produce energy for the cell

• To ensure newly formed cells have exact copies of DNA

• To break down nutrients

• To remove waste from the cell

Open Ended

Describe the process that occurs during DNA replication when the double helix unwinds and separates. Why is this step important?

Fill in the Blanks

During DNA replication, complementary

pair with the exposed bases.

Multiple Select

Which of the following are steps involved in DNA replication?

• The double helix unwinds

• DNA helicase unzips the strands

• Complementary nucleotides pair with exposed bases

• DNA is translated into RNA

Multiple Choice

What is the result of DNA replication in terms of the DNA molecules produced?

• Two identical DNA molecules, each with one original and one new strand

• One DNA molecule with two new strands

• Two DNA molecules with only original strands

• Four DNA molecules with mixed strands

Open Ended

Explain how cells maintain the accuracy of DNA replication and what can happen if errors are not corrected.
