Question

For translation to take place, which of the following would not be required to be present?

Options

• DNA

• mRNA

• tRNA-amino acid complex

• rRNA

Answer 1

DNA

Explanation:

Translation is the second major step in protein synthesis, occurring in the cytoplasm at the ribosomes. While DNA is the master blueprint that stores genetic information, it is only directly required for the first step, transcription, where its code is copied into a portable molecule of mRNA. Once transcription is finished, the DNA remains in the nucleus, and the actual assembly of the protein relies entirely on mRNA as a template, the tRNA-amino acid complex to bring the correct building blocks, and rRNA to provide the structural and catalytic framework for the ribosome.
