An investigator shall retain records needed to be preserved under this part for a period of two years following the date a marketing operation is approved for the drug for the explanation for which it is being investigated
Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.
The right answer is: <span>D. the formation of clouds
</span>Condensation is the second stage of the water cycle. The water vapor circulating in the atmosphere will encounter a colder air and it will turn into droplets, this phenomenon is called condensation.<span>
Water droplets accumulate in the form of clouds of different shapes, density, and altitude. This phenomenon is called condensation. Water vapor travels on the surface of the earth in the form of clouds.</span>
