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. A major difference between DNA replication in prokaryotes and eukaryotes is :   replication is conservative in prokaryotes   DNA amylase performs the function of DNA helicase in prokaryotes   prokaryotes do not use Topoisomerase in the replication process   there is only one replication origin in prokaryotes.   Half-n-half Clue   3. 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   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. 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   6. 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   7. What does transformation involve in Bacteria ?   the creation of a strand of DNA from RNA   assimilation of external DNA into a cell   the infection of cells by a phage DNA molecule   the creation of a strand of RNA from DNA   Half-n-half Clue
