Answer:
The correct answer is B, The theory that states the genetic information flows only in one direction. The Central Dogma of Biology is a theory that explains the flow of genetic information within cells. It states that genetic information flows in one direction, from DNA to RNA to proteins. DNA (deoxyribonucleic acid) contains the genetic instructions for making proteins, which are responsible for many functions in the body. RNA (ribonucleic acid) is a molecule that is involved in the transfer of information from DNA to proteins. The Central Dogma explains that information flows from DNA to RNA through a process called transcription, and from RNA to proteins through a process called translation.
