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 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   3. 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   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. 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   Half-n-half Clue   6. A major difference between DNA replication in prokaryotes and eukaryotes is :   prokaryotes do not use Topoisomerase in the replication process   DNA amylase performs the function of DNA helicase in prokaryotes   replication is conservative in prokaryotes   there is only one replication origin in prokaryotes.   Half-n-half Clue   7. The enzyme that stitches Okazaki fragments together (along the lagging strand) is called :   Topoisomerase   Holoenzyme   DNA Polymerase II   DNA Ligase   Half-n-half Clue
