DNA does all but which of the following?

siniylev [52]

Answer:

The correct answer will be option-is read by ribosomes during the process of translation.

Explanation:

The DNA is a nucleic acid made up of nucleotides which serves as a genetic material of the cell. It stores the information required by the cell in the form of codons made up of nitrogenous bases. The DNA after transcription forms a messenger molecule called mRNA which is read by the ribosomes to code for specific amino acid which binds to form the proteins, the building block of the body.

Since the mRNA is read by the ribosomes during translation and not DNA directly, therefore, the selected option is the correct answer.
