Option B

An important factor in Oswald Avery's ability  to identify the "transforming principle” as  DNA was the fact that proteins contain very little phosphorus

Oswald Avery manifested an approach to clarify this transforming principle. He then conveyed a range of chemical tests to discover out what it was. Scientists did comprehend that genes were placed on chromosomes and that chromosomes consisted of DNA and proteins.

At the event, yet, proteins resembled to be a better alternative for the genetic material. Chemical analysis explicates that the proportions of elements in the decoction exactly resembled those observed in DNA. Proteins comprise substantially no phosphorus.
