Which of the following is not true of the two strands of DNA?

• They are antiparallel

• The strands are held together by hydrogen bonds

• The strands are held together by covalent bonds

• The two strands are complementary to each other

During which phase of the cell cycle is DNA replicated?

• Prophase

• G1 phase

• G2 phase

• S phase

Which of the following statements is NOT true of DNA replication?

• Replication begins at the origin of replication

• Two replication forks are formed from each origin of replication

• Replication starts at the replication forks

• Multiple origins of replication would be found on a chromosome

Match the DNA replication enzyme with its function.

• Joins together Okazaki fragments

• Topoisomerase

• Unwinds or unzips DNA

• Helicase

• Builds new DNA strand

• Primase

• Makes RNA primer

• Ligase

Which strand must be made in Okazaki fragments because the direction of replication is moving away from the replication fork?

• Leading strand

• Lagging strand

• Both strands are replicated in fragments

• Neither strand is replicated in fragments
