While doing research on deep-sea vents, you discover a very simple new life form. After some initial analysis, you find that this life form contains small fragments of DNA, small complementary RNA fragments, and proteins. Fortuitously, you collected two strains, one that is purple and one that is yellow.
-You wish to discover which of those three molecules could be the genetic material. You heat-kill some of the purple life form and subject three different homogenized samples to different enzymes: DNase, RNase, or protease. Which sample will NOT transform yellow into purple?

Quizplus · Accepted Answer

DNase will degrade DNA, which is the genetic material. Without DNA, the transformation from yellow to purple cannot occur.
