View the animation below, then complete the quiz to test your knowledge of the concept.



1.

Arrange the following proteins in the proper order in which they participate in DNA replication.
1 = Primase
2 = Helicase
3 = Single-strand binding proteins
4 = DNA polymerase
A)1, 2, 3, 4
B)1, 3, 2, 4
C)2, 3, 1, 4
D)2, 3, 4, 1
E)2, 4, 3, 1
2.

What is the function of the enzyme primase during DNA replication?
A)to unwind the double helix to prime it for replication
B)to prime DNA for replication by preventing the formation of knots
C)to add a DNA primer to enable replication of DNA
D)to add a RNA primer to enable replication of DNA
E)to correct errors made during DNA replication
3.

The short DNA segments formed on the discontinuously replicated strand are called
A)Kawasaki fragments.
B)Nagasaki fragments.
C)Miyazaki fragments.
D)Okazaki fragments.
E)Suzuki fragments.
4.

As helicase unwinds the DNA molecule, the separated strands are kept apart by DNA polymerase.
A)True
B)False
5.

DNA replication can begin at any site along the DNA molecule.
A)True
B)False
