D) are parallel and are the mirror images of each other. Question 20 (5 points) In a series of experiments, Oswald Avery treated heat-killed nonvirulent
S
bacteria with enzymes that degraded the proteins, DNA, and RNA of the S bacteria, then mixed this with nonvirulent
R
bacteria.
S
cells grew in all cases except the samples with degraded DNA. What did this demonstrate? A) Protein, DNA, and RNA from the S bacteria are all necessary for bacterial transformation to occur. B) DNA from the
S
bacteria is necessary for bacterial transformation to occur. C) RNA from the S bacteria is necess.ov fort hoctoin
