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

• A. Replication
• B. Central Dogma
• C. Transcription and Translation
• D. Genetic Inheritance

Answer: (B)

The flow of genetic information from DNA to RNA to protein is described by the Central Dogma of molecular biology. It captures how information stored in DNA is first transcribed into RNA, and then translated into a protein, linking the genetic code to functional molecules in the cell. Transcription and translation are the two steps that carry out these processes, but naming the overarching concept as Central Dogma reflects the directional flow from DNA to RNA to protein. Replication is about copying DNA for cell division, not expressing genes as proteins, and genetic inheritance is about passing genes to offspring, not the mechanism of gene expression.
