Multiple choice

Your Performance  

1.

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 :

  DNA Polymerase II

  Primase

  DNA Polymerase I

  DNA Polymerase III

  Half-n-half Clue
 

2.

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

  Gyrase

  Topoisomerase

  Ligase

  Helicase

  Half-n-half Clue
 

3.

The enzyme (made of proteins and RNA) that elongates chromosomes by adding TTAGGG sequences to the end of existing chromosomes is :

  Telomerase

  Exonuclease

  Endonuclease

  Amylase

  Half-n-half Clue
 

4.

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
 

5.

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 :

  Primase

  Topoisomerase

  Helicase

  DNA Polymerase II

  Half-n-half Clue
 

6.

A major difference between DNA replication in prokaryotes and eukaryotes is :

  DNA amylase performs the function of DNA helicase in prokaryotes

  replication is conservative in prokaryotes

  prokaryotes do not use Topoisomerase in the replication process

  there is only one replication origin in prokaryotes.

  Half-n-half Clue
 

7.

DNA Polymerase III is actually an aggregate of several different protein subunits. So it is often called a :

  Holoenzyme

  Primeosome

  replisome

  None of the above

  Half-n-half Clue
