Question

Fill in the blanks to complete the narrative and choose the right word from the table.

In 1952, (26) continued researching to determine what is the genetic material. The researchers used (27) which is a virus that infects (28). The body of the virus is composed of (29) and inside the capsid/head contains (30). In a two part experiment they radioactively labeled 35S which would be incorporated in (31) and 32P which would be incorporated into (32) upon infection. They allowed the virus to attach to the (33) and infect the bacteria. They sheared off the virus using a blender, centrifuged, and analyzed the supernatant and the pellet. If (34) is the transforming principle, the 35S would be found in the pellet not the supernatant. If (35) is the transforming principle, 32P would be found in the pellet not the supernatant. The 32P was found in the pellet and 35S was found in the supernatant. This data suggests that (36) not Protein is the transforming principle.

Explanation / Answer

26-Harshey and chase

27-T2 bacteriophage

28- Ecoli.

29- protein

30-DNA IS GENETIC MATERIAL

31-protein coats of the bacteriophages,sulfur containing material entered the bacterial cell

32- radioactive DNA,sulfur-free enters the bacterial cell after phage adsorption

33-Ecoli.

34-protein

35-DNA,Bacterial cells formed a pellet at the bottom, while the viral particles remained in the supernatant

36-DNA
