Which of the following sequences correctly represents flow of genetic info?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. DNA --> RNA --> Protein.
This sequence represents the Central Dogma of Molecular Biology, proposed by Francis Crick. Information stored in DNA is first copied into RNA, messenger RNA (mRNA) specifically, through a process called Transcription. This RNA then travels to the ribosomes, where the code is read and used to assemble amino acids into a specific Protein during Translation. This flow ensures that the genetic "blueprint" in the nucleus is accurately expressed as functional molecules that perform cellular tasks.
