Which of the following represents the correct order in the flow of genetic information?
A)tRNA → DNA → proteins
B)mRNA → tRNA → proteins
C)DNA → mRNA → proteins
D)rRNA → mRNA → proteins
E)DNA → tRNA → mRNA

Question

Quizplus · Accepted Answer

The correct order in the flow of genetic information is DNA (where the genetic information is stored) being transcribed into mRNA (which carries the genetic information out of the nucleus), and then mRNA being translated into proteins by ribosomes. Option A is incorrect because tRNA only carries amino acids to the ribosome during translation, but it is not involved in the flow of genetic information. Option B is incorrect because mRNA is transcribed from DNA, not the other way around. Option D is incorrect because rRNA is a component of the ribosome and is involved in protein synthesis, but it does not carry genetic information. Option E is incorrect because tRNA is not involved in the flow of genetic information between DNA and proteins.
