DNA Replication

Which of the following statements is FALSE about DNA replication?

• DNA replication is semi-conservative.

• DNA replication occurs in the S phase.

• The leading strand is synthesized continuously.

• DNA polymerase initiates DNA synthesis without a primer.

Which of the following is the primary function of the primase during DNA replication?

• unwinding the DNA helix

• joining Okazaki fragments

• synthesizing a short RNA primer

• adding DNA nucleotides to the growing DNA strand

In the lagging strand, the Okazaki fragments are joined by the ​ (a)   .

• ligase
• primase
• helicase
• DNA polymerase

The DNA Polymerase synthesizes the leading strand ​ (a)   , while the lagging strand is synthesized​ (b)   .

• continuously
• discontinuously

Given the DNA template strand

5' A G C T A A G T C G A C G C T 3',

what is the complementary DNA strand?

What is the primary importance of DNA replication?

• It repairs damaged DNA sequences.

• It allows for genetic variation in organisms.

• It produces RNA molecules for protein synthesis.

• It ensures each new cell has an identical copy of DNA.

Arrange the following steps in the proper order for DNA replication.

• Helicase unwinds the DNA helix.

• Primase synthesizes an RNA primer.

• DNA polymerase adds new nucleotides to form complementary strands.

• Ligase joins Okazaki fragments on the lagging strand.
