The strand that is copied in a continuous way as read from the 3’ to 5’ direction, is called the _________.

• Leading strand

• Lagging strand

• Okazaki strand

• Primer strand

Which enzyme binds Okazaki fragments?

• Helicase

• DNA polymerase

• Ligase

• Topoisomerase

What builds a new DNA strand by adding complementary bases?

• DNA polymerase

• Helicase

• Ligase

• RNA primer

What stabilizes the DNA molecule during replication?

• Helicase

• DNA polymerase

• Ligase

• Single-strand binding proteins.

The strand that is copied discontinuously because it is traveling away from helicase is called the _________.

• Leading strand

• Lagging strand

• Okazaki strand

• Primer strand

Why is replication called 'semi-conservative'?

• Each new DNA molecule has one old strand and one new strand

• Both strands are new

• Both strands are old

• It conserves energy.

What is the role of topoisomerase in DNA replication?

• Unwinds DNA

• Uncoils (breaks) DNA strand upstream of the replication fork

• Binds Okazaki fragments

• Adds nucleotides.

Which enzyme attaches to the primer during DNA replication?

• Helicase

• DNA polymerase

• Ligase

• Topoisomerase

What is the enzyme that unwinds DNA?

• DNA polymerase

• Helicase

• DNA Ligase

• Topoisomerase

Which enzyme binds backbone bonds in Okazaki fragments?

• DNA Ligase

• Helicase

• DNA polymerase

• Topoisomerase
