It is not c or d. I think it is a.
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.
Look to see if the compound is ionic or not, then follow the rules for prefixes and suffixes of the compound.
Answer:
B. Bacteria can exchange genes for resistance to antibiotics in this way.
Explanation:
Even though conjugation requires cell-to-cell contact, it can occur between distantly related bacteria
