In a series of experiments, 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 necessary for bacterial transformation to occur.
d. protein from the s bacteria is necessary for bacterial transformation to occur.

The correct answer would be option B.

Avery experiment proved that DNA is used as the genetic material in most of the living organisms.

It can be explained with the help of observation that when the S bacteria were treated with DNAase, they could not transfer their DNA to the R bacteria. Consequently, R bacteria did not transform into S bacteria.

In contrast, when these bacteria were treated with protease or RNAase, they could transfer DNA easily due to which R bacteria could easily transformed into S bacteria.

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.

answer: that would be cheating
