Translation involves all of the following types of molecules except:
a
DNA
b amino acids
С
tRNA
d mRNA

A. DNA

Explanation:

Translation occurs in the ribosomes after leaving the nucleus, and does not involve DNA molecules.

Translation involves tRNA which binds to mRNA.

Then, amino acids are created based on what has been encoded.

So, A is the correct answer.

DNA

Explanation:

The translation is the process of the sequence of nucleotides in mRNA into the order of amino acids in a polypeptide (protein).

Protein synthesis is performed in a process called translation in which the alphabet of four-letter nucleic acids (A; G; C; T) must be translated into the language of a protein with 20 different amino acids.
