Which of the following sequences correctly represents the flow of genetic information?
DNA → RNA → Protein
The standard flow of genetic information in cells is described by the Central Dogma of Molecular Biology, proposed by Francis Crick in 1958.
DNA → RNA → Protein
Step 1 — Transcription: The genetic information stored in DNA is copied into messenger RNA (mRNA) by the enzyme RNA polymerase.
Step 2 — Translation: The mRNA is read by ribosomes, where transfer RNA (tRNA) brings amino acids that are linked together to form a protein.
Some viruses (retroviruses) use reverse transcription (RNA → DNA), but the standard, universal flow is DNA → RNA → Protein.
Hence, the answer is option C.
