DNA → _____ → Proteins

Question

Quizplus · Accepted Answer

According to the central dogma, DNA is first transcribed into messenger RNA (mRNA), which then serves as a template for protein synthesis. Therefore, the molecule that should go in the blank is mRNA, as it transfers the information from DNA to ribosomes where proteins are synthesized. Option A (mRNA making proteins directly) is incorrect because mRNA serves as a template for protein synthesis, but it does not directly make proteins. Option B (rRNA making proteins directly) is also incorrect because rRNA is a component of ribosomes, which are involved in protein synthesis, but it does not make proteins directly. Option D (tRNA transferring information from DNA) is incorrect because tRNA transfers amino acids to the ribosomes, but it does not transfer information from DNA.
