AGenes to mRNA to protein
BProtein to mRNA to genes
CmRNA to genes to protein
DGenes to protein to mRNA
Answer & Solution
Correct answer: A. Genes to mRNA to protein
1. Genes made of DNA are copied into mRNA by transcription.
2. The mRNA sequence is then read by the translation machinery to build a protein.
3. So the order runs genes to mRNA to protein, and none of the reversed orders describes the normal flow.
