DNA Replication Quiz

What is the semiconservative model of DNA replication?

• Each daughter DNA molecule has no parent strands.

• Each daughter DNA molecule has two parent strands.

• Each daughter DNA molecule has one parent strand and one new strand.

• Each daughter DNA molecule has two new strands.

What is the first step in the process of DNA replication?

• Synthesis of new nucleotides

• Formation of Okazaki fragments

• Unwinding of the double helix

• Sealing of DNA fragments

What is the role of helicase in DNA replication?

• It unwinds the DNA double helix.

• It seals the gaps between DNA fragments.

• It synthesizes new DNA strands.

• It forms hydrogen bonds between base pairs.

In which direction are the newly synthesized DNA strands formed?

• Random direction

• 5' to 3' direction

• 3' to 5' direction

• Both directions simultaneously

What are Okazaki fragments?

• Short segments of DNA synthesized on the lagging strand

• Proteins that bind to DNA

• Continuous strands of DNA

• Enzymes that catalyze DNA synthesis
