Question

which one of the following does not play a role in translation?
○ ribosomes
○ amino acids
○ anticodon
○ trna
○ dna

Explanation:

1. Ribosomes: Ribosomes are the site of translation, where protein synthesis occurs. So they play a role.
2. Amino acids: Amino acids are the building blocks of proteins, and during translation, they are linked together to form a polypeptide chain. So they play a role.
3. Anticodon: The anticodon is part of tRNA. It pairs with the codon on mRNA, helping to bring the correct amino acid to the ribosome during translation. So it plays a role.
4. tRNA: tRNA (transfer RNA) is responsible for bringing the correct amino acids to the ribosome based on the codons on mRNA. It is essential for translation.
5. DNA: Translation is the process of synthesizing proteins from mRNA. DNA is involved in transcription (where mRNA is synthesized from DNA), but not directly in translation. During translation, the template is mRNA, not DNA.

Answer:

E. DNA
