Question

which describes something that occurs during translation?
a dna template is used to create an mrna strand.
a trna template is used to create a dna strand.
a trna template is used to create an mrna strand.
an mrna template is used to create an amino acid chain.

Explanation:

To solve this, we recall the process of translation in biology. Translation is the step where the mRNA (messenger RNA) is used as a template to assemble amino acids into a polypeptide (amino acid chain) with the help of tRNA (transfer RNA) and ribosomes. Let's analyze each option:

• Option A: Using a DNA template to create mRNA is transcription, not translation.
• Option B: tRNA is not used to create DNA, and this is not part of translation (or normal cellular processes in this way).
• Option C: tRNA does not act as a template to create mRNA; mRNA is made from DNA in transcription.
• Option D: This matches the definition of translation, where mRNA is the template for building an amino acid chain (polypeptide).

Answer:

D. An mRNA template is used to create an amino acid chain.
