Which of the following best describes the central dogma of biology?

• A. DNA is transcribed into RNA, which is then translated into protein.
• B. Proteins are transcribed into RNA, which is then translated into DNA.
• C. DNA is translated into protein, which is then transcribed into RNA.
• D. RNA is transcribed into DNA, which is then translated into protein.

Answer: (A)

Verified step by step guidance

1. Understand the central dogma of molecular biology, which describes the flow of genetic information within a biological system.
2. The central dogma involves two main processes: transcription and translation.
3. During transcription, the genetic information in DNA is copied into messenger RNA (mRNA).
4. In translation, the mRNA is used as a template to synthesize proteins, which are chains of amino acids.
5. Review the options given and identify the sequence that correctly follows the process: DNA -> RNA -> Protein.
