3)DNA ligases are used with ___________ to insert DNA fragments into plasmids 
  

4)The common commercially available DNA ligases were originally discovered in bacteriophage ________ 
  

5)If the ambient temperature exceeds Tm, homologous pairing of the sticky ends will not occur because the high temperature disrupts ________
  

6)A DNA strand has the following bases: G T C A G C A. What are the bases on its complimentary strand? 
  

7)T4 DNA ligase is similar to E. coli DNA ligase, except that ATP is a cofactor rather than NAD. Besides ligated DNA, another product is
