Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information within a biological system.
The central dogma is often summarized as DNA -> RNA -> Protein, indicating the process of transcription and translation.
Transcription is the process where the DNA sequence is copied into messenger RNA (mRNA). This process is unidirectional, meaning it goes in one direction: from DNA to RNA.
Translation is the process where the mRNA is used as a template to synthesize proteins. This process is also unidirectional, going from RNA to protein.
Based on the central dogma, the correct interpretation is that it refers to unidirectional processes, specifically unidirectional transcription and translation.
