Answer:
The correct answer will be- nucleus is the site for the formation of blueprint (mRNA) in transcription.
Explanation:
The process of formation of a protein or polypeptide from mRNA is known as the translation which takes place in the cytoplasm.
In the given question, the proteins produce takes the role of an enzyme later but the pathway of formation of the protein is the same that is transcription (production of mRNA) and the translation.
The blueprint of the protein is known as the mRNA or messenger RNA which is synthesized by the process of transcription which takes place in the nucleus in the eukaryotes.
Thus, the nucleus is the site for the formation of the blueprint (mRNA) in transcription.
