Question

What is the correct gene expression pathway?

• A. Gene―transcription―mRNA―translation―protein
• B. Gene―translation―mRNA―transcription―protein
• C. Transcription―gene―translation―mRNA―protein
• D. Gene―mRNA

Answer 1

The correct option is A Gene―transcription―mRNA―translation―protein

Gene expression
A process by which the genetic information is used to synthesise functional gene products is known as gene expression.
Gene―transcription―mRNA―translation―protein is the correct gene expression pathway.
$\bullet$Transcription is the process of synthesis of mRNA from the DNA template. Here, the information is passed from DNA to mRNA.
$\bullet$The process involving synthesis of a polypeptide chain based on the information coded in mRNA is called translation. It leads to the formation of protein.
Final answer
(C) Gene―transcription―mRNA―translation―protein
