Chemically, what is the route from genes to their expression?
A) DNA to proteins to RNA
B) DNA to RNA to proteins
C) Proteins to DNA to RNA
D) RNA to DNA to proteins

Question

Quizplus · Accepted Answer

The route from genes to their expression is called the central dogma of molecular biology. It involves the process of transcription where DNA is converted into RNA and then translation where RNA is converted into proteins. Therefore, the correct route is DNA to RNA to proteins. Choice A is incorrect because it reverses the order of RNA and proteins. Choice C is incorrect because proteins cannot be converted back into DNA. Choice D is incorrect because RNA cannot be converted into DNA in a biological system.
