1. The enzyme that replaces the nucleotides of the RNA primer with the appropriate DNA nucleotides is :   DNA Polymerase II   RNA Polymerase   DNA Ligase   DNA Gyrase   Hint Half-n-half Clue   2. The end of a DNA strand that has a phosphate group attached to the number 5 carbon of its terminal deoxyribonucleotide is called :   The 5 prime end (5')   The 3 prime end (3')   N-Terminus   C-Terminus   Half-n-half Clue   3. 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 :   Helicase   Topoisomerase   DNA Polymerase II   Primase   Half-n-half Clue   4. 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   5. In DNA, mutations at G-C sequences occur quite frequently since 5-methyl cytosine easily deaminates to form :   Thymine   Adenine   Guanine   Cytosine   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 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
