In samples of DNA isolated from two unidentified species of bacteria, adenine makes up 32 and 17%, respectively, of the total bases. 1. What relative proportions of adenine, guanine, thymine, and cytosine would you expect to find in the two DNA samples? (hint: bacterial DNA is circular plasmid) 2. What assumptions have you made? One of these bacteria was isolated from a hot spring 64 degree C. Which DNA came from this thermophilic bacterium? What is the basis for your answer? (hint: consider bonding strength A-T or G-C)
