The _____ is a theory that states that information flows from DNA to RNA to proteins.

• A. Central dogma
• B. Genetic code
• C. Transcription
• D. Replication

Answer: (A)

The central dogma states that information flows from DNA to RNA to proteins. This captures the directionality of genetic information: DNA is transcribed into RNA, and RNA is translated into proteins. DNA replication is the separate process by which DNA is copied for cell division, not the overall flow of information to RNA and protein. The genetic code is the set of rules that translates RNA codons into amino acids during translation, not the direction of information flow itself. Transcription is the process of making RNA from DNA, while replication duplicates DNA. Together, these ideas describe how genetic information moves from the storage form to the functional products in the cell.
