What concept describes the flow of genetic information from DNA to RNA to protein?

• A. DNA replication
• B. Transcription
• C. Translation
• D. Central Dogma

Answer: (D)

The central dogma describes how genetic information moves from DNA to RNA to protein. DNA holds the genetic code, transcription copies that code into messenger RNA, and translation uses that RNA to build a protein. This overall flow explains how genes are expressed, not just how DNA is copied. DNA replication is about copying DNA for cell division, and transcription or translation alone cover only part of the process, whereas the central dogma captures the full sequence from DNA to functional protein.
