Multiple choice

Your Performance  

1.

The enzyme that accomplishes the unwinding of the original double stranded DNA molecule, once supercoiling has been eliminated, by breaking the hydrogen bonds that hold the two strands together is :

  DNA Polymerase II

  Topoisomerase

  Helicase

  Primase

  Half-n-half Clue
 

2.

The enzyme that (during replication) proceeds along one of the strands of a DNA molecule adding deoxy-nucleotide-triphosphates to hydrogen bond with their appropriate complementary dNTP on the other single strand and to form a covalent phosphodiester bond with the previous nucleotide of the same strand is called :

  Primase

  DNA Polymerase III

  DNA Polymerase I

  DNA Polymerase II

  Half-n-half Clue
 

3.

The enzyme responsible for initiating the unwinding of double-stranded DNA (eliminating supercoiling) by nicking a single strand of the DNA molecule is :

  Topoisomerase

  Helicase

  Ligase

  Gyrase

  Half-n-half Clue
 

4.

Because DNA polymerase III can only act from 5' to 3', continuous strand growth can be achieved only along one of the template strands (Leading strand) and strand growth along the other strand must occur discontinuously resulting in the production of a series of short sections of new DNA called :

  Replicon fragments

  Okazaki fragments

  Klenow fragments

  None of the above

  Half-n-half Clue
 

5.

The enzyme X removes RNA primers attached by Primase and this gap is then filled in by DNA Polymerase I. The enzyme X is :

  RNase H

  DNA amylase

  DNA ligase

  Reverse Transcriptase

  Half-n-half Clue
 

6.

The enzyme that creates a short RNA oligonucleotide at initiation sites where replication is to be carried out is called :

  Primase

  DNA Ligase

  DNA Gyrase

  Exonuclease

  Half-n-half Clue
 

7.

The enzyme that stitches Okazaki fragments together (along the lagging strand) is called :

  DNA Polymerase II

  Topoisomerase

  DNA Ligase

  Holoenzyme

  Half-n-half Clue
