Each group of questions below concerns an experimental or laboratory situation or data. In each case, first study the description of the situation or data. Then choose the one best answer to each question. In the 1940's, Avery MacCleod, and McCarty transformed nonencapsulated bacteria into encapsulated forms by growing the nonencapsulated cells in a culture containing an extract made from dead encapsulated cells. The transformed cells produced colonies of encapsulated bacteria. Three different procedures and their results are outlined below. Procedure 1: Extract made from dead encapsulated cells added to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow.

Procedure II: Extract made from dead encapsulated cells treated with protein-degrading enzymes before adding extract to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow.

Procedure III: Extract made from dead encapsulated cells treated with DNAse (an enzyme that selectively destroys DNA) before adding extract to culture medium. Nonencapsulated bacteria added to culture medium. Results: Only nonencapsulated bacteria grow. A resonable conclusion to draw from the results of the experiment is that

A DNA is the genetic material
B DNA replication is semiconsevative
C DNA is a double helix
D DNA is translated into protein
E mutation is a change in the genetic material​
