Question

which statement describes translation?
○ dna makes proteins.
○ dna makes rna.
○ proteins act in cells.
○ rna makes proteins.

Explanation:

To determine the correct statement about translation, we recall the central dogma of molecular biology. Transcription is the process where DNA makes RNA, and translation is the process where RNA (specifically mRNA) is used to synthesize proteins. Let's analyze each option:

• "DNA makes proteins" is incorrect because DNA does not directly make proteins; it goes through RNA.
• "DNA makes RNA" describes transcription, not translation.
• "Proteins act in cells" is a general statement about protein function, not translation.
• "RNA makes proteins" correctly describes translation, where ribosomes use the information in mRNA (a type of RNA) to assemble amino acids into proteins.

Answer:

D. RNA makes proteins (assuming the options are labeled A - D as: A. DNA makes proteins, B. DNA makes RNA, C. Proteins act in cells, D. RNA makes proteins)
