Question

question 14
which best represents the flow of genetic information in a cell?
protein->trna->dna
dna->protein->trna
mrna->dna->protein
dna->mrna->protein

Explanation:

According to the central dogma of molecular biology, genetic information flows from DNA to mRNA (through transcription) and then from mRNA to protein (through translation). tRNA is involved in translation but the flow is not from protein to tRNA to DNA. Also, the flow is not from DNA to protein directly (needs mRNA intermediate) and not from mRNA to DNA (except in reverse - transcription which is not the general flow in a cell).

Answer:

DNA->mRNA->Protein
