Understanding DNA Replication

What is the primary role of DNA in living organisms?

• To provide energy

• To serve as a genetic blueprint

• To protect against diseases

• To transport nutrients

During which process does DNA replication occur to support growth?

• Cell division

• Protein synthesis

• Photosynthesis

• Respiration

Which phase of the cell cycle is responsible for DNA replication?

• Synthesis phase

• G1 phase

• Mitosis

• G2 phase

What happens during the synthesis phase of the cell cycle?

• Cells grow in size

• Cells divide

• Proteins are synthesized

• DNA is copied

Why is it important for DNA to replicate accurately during cell division?

• To prevent cell death

• To speed up cell division

• To ensure genetic diversity

• To maintain identical genetic information in new cells
