1. An enzyme that recognizes and cuts DNA only at a particular sequence of nucleotides is often called :   Restriction endonuclease   RNA polymerase   Photolyase   DNA glycosylase   Hint Half-n-half Clue   2. The enzyme that stitches Okazaki fragments together (along the lagging strand) is called :   DNA Polymerase II   DNA Ligase   Topoisomerase   Holoenzyme   Half-n-half Clue   3. 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   4. 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   5. 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   6. A repeating DNA sequence at the end of chromosomes that prevents them from losing base pair sequences at their ends and from fusing together is called :   A Telomere   A Telomerase   A replicon   None of the above.   Half-n-half Clue   7. 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
