The answers are DNA contains genetic material and X-ray diffraction.

Explanation:

For question 3 the answer is DNA contains genetic material!!

Hershey and Chase used radioactive isotopes to label a bacteriophage. ... After allowing the bacteriophage to infect the bacteria, the presence of radioactive phosphorus in the bacteria confirmed that DNA was the genetic material found in genes!!

For question number 4 the answer is X-ray diffraction!!

X-ray crystallography

Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.

Hope this helps!! ;)
