AlladinOne [14]

Answer:

Option (1).

Explanation:

The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.

The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.

Thus, the correct answer is option (1).
