2) e. coli bacteria are used in many genetic studies because it reproduces itself every 20 minutes. it has been found that these bacteria can absorb genes from other dead, ground-up bacteria, a process known as transformation. dnase is an enzyme that destroys dna molecules by breaking bonds within the sugar-phosphate backbone of the double helix. proteases are an array of enzymes that destroy protein structure, and thus, function. in the experiment below, identify which test tubes will show transformation & justify your response. tube contents transformation (+ or -) justification 1 ground up e coli + living e coli 2 ground up e coli treated with dnase + living e coli 3 ground up e coli treated with proteases + living e coli 4 ground up e coli treated with dnase & proteases + living e coli
