The second one
One gene for a particular trait
Answer:
The correct answer will be option-E
Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
Populations
communities
ecosystem
biosphere
