Question

Which of the following will be the correct gene expression pathway?

• A. $Gene \rightarrow mRNA \rightarrow transcription \rightarrow translation \rightarrow protein$
• B. $Transcription \rightarrow gene \rightarrow translation \rightarrow mRNA \rightarrow protein$
• C. $Gene \rightarrow transcription \rightarrow mRNA \rightarrow translation \rightarrow protein$
• D. $Gene \rightarrow translation \rightarrow mRNA \rightarrow transcription \rightarrow protein$

Answer 1

Answer: (C)

Central dogma refers to a biological mechanism that includes both transcription and translation of genetic information. In this process, the genetic message is encoded in DNA transfer to mRNA in a unidirectional way by transcription, and protein synthesis occurs through translation.
$\text{Gene} \rightarrow \text{transcription} \rightarrow \text{mRNA} \rightarrow \text{translation} \rightarrow \text{protein}$
