Which of the following enzymes is responsible for synthesizing the new DNA strand?

• DNA polymerase

• Helicase

• Primase

• DNA ligase

What is the difference between leading and lagging strands?

• DNA is synthesized in a 5' to 3' direction on the lagging strand and a 3' to 5' direction on the leading strand

• DNA is synthesized in a 3' to 5' direction on the lagging strand and a 5' to 3' direction on the leading strand

• DNA is synthesized continuously on the leading strand and discontinuously on the lagging strand

• DNA is synthesized discontinuously on the leading strand and continuously on the lagging strand
