What was originally considered to be the genetic material? Why? Correct Answer-Proteins were considered to be the genetic material because they were inherently more complex than DNA. Avery, McCarty, MacLeod experiment Correct Answer-First, think about Griffith's experiment and how even heat killed strains of S. pneumococcus still led to death of non pathogenic cells ⁃ Process: Grind up virulent cells, isolate the active genetic material ('transforming principle') and infuse it into non...

What statement best distinguishes scientific hypotheses from scientific theories? - ANSWER Hypotheses are usually narrower in scope; theories have broader explanatory power. A controlled experiment ____________. - ANSWER includes at least two groups, one of which does not receive the experimental treatment In trying to determine whether DNA or protein is the genetic material, Hershey and Chase made use of which fact? - ANSWER DNA contains phosphorus, whereas protein does not. In analyzi...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? CORRECT ANSWER The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: CORRECT ANSWER The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? CORRECT ANSWER The Gram + cell stains ...
