Nitrogen and carbon are more abundant in proteins than sulfur. Why did Hershey and Chase use radioactive sulfur instead of nitro
lora16 [44]

Answer:

Hershey and Chase experiment confirms that DNA is the genetic material of the living organism, not the RNA or protein. They also got a noble prize for this discovery.

Hershey and Chase use the radioactive sulfur to label the proteins and distinguish them from the DNA because DNA do not contain sulfur. The radioactive label phosphorus was used to label the DNA as phosphorus is specific to DNA as they wants to know exactly the genetic material. They do not use the radioactive carbon and nitrogen because both carbon and nitrogen are present in DNA and RNA. This labeling may produce confused result as it label both DNA as well as protein. The result o radioactive phosphorus and sulfur determines that DNA is the genetic material of the organism.

4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of
motikmotik

Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°
