Answer is (E) : Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Let me explain you why. Hershey and Chase conducted their experiment to show what is the genetic material that passes from one generation to another generation. Is it protein or DNA? For explaining this, they allowed the virus to grow in the presence of two different radio active elements.
In one set they grew viruses in the presence of P-32 radio-active element
In another set they grew viruses in the presence of S-35 radio active element.
The reason why they choose these two radio-active element was, phosphorus is present in DNA but not in proteins and similarly sulphur is found in proteins but not DNA.
These viruses were allowed to infect bacteria and the later was observed to be radio-actively labelled with P-32 but not S-35. This clearly showed that DNA is the genetic material which was passed from virus to bacteria.
Now if you choose Nitrogen for labeling, it won't help you in getting any conclusion since nitrogen is present in both proteins and DNA.
I believe it is B.
Don’t hate me if I am wrong :,)
In most animals, the diploid state of the life cycle is much larger than the haploid state.
<h3>What is life cycle?</h3>
The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.
The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.
During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.
For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.
Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

Answer:
The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
