1)Organisms termed his^- are considered prototrophic for histidine.              

2.         Each gene mutates at a characteristic frequency.      

3.         DNA polymerase is able to proofread the DNA sequence.      

4.         Mutations are likely to persist after SOS repair, but not after light-induced or excision repair.       

5.         The Ames test determines antibiotic sensitivity of a bacterium.        

6.         Double-stranded DNA enters the recipient cell during transformation.         

7.         Plasmids often carry the information for antibiotic resistance.          

8.         F plasmids and oftentimes R plasmids are both able to code for production of a pilus.        

9.         Transposons may leave a cell by incorporating themselves into a plasmid.               

10.       Crown gall is caused by a prokaryote plasmid that can be expressed in plant cells.
