Reptile [31]

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.

Elina [12.6K]

Answer:

The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .

eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.

In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
