What concept describes the transfer of genetic information from DNA to mRNA to protein as being irreversible?

The concept that describes the transfer of genetic information from DNA to mRNA to protein as being irreversible is the central dogma of molecular biology. This principle outlines the flow of genetic information within a biological system and defines the processes of transcription and translation.

In this framework, DNA is transcribed into mRNA, which is then translated into a protein. This chain of events is unidirectional, meaning that once information is expressed as a protein, it cannot be reverted back to its original DNA form. This irreversibility is critical for understanding how genetic information is utilized in cells to produce functional proteins that carry out diverse biological functions.

The other concepts listed, such as the genetic code, which refers to the specific sequences that determine amino acid placement, and the transcription process, which is just one part of the central dogma, do not capture the overall flow or the irreversible nature of this information transfer as effectively as the central dogma does.
