Question

state the central dogma of molecular biology.
a rna → dna → protein
b dna → rna → protein
c none of the above
d dna → protein → rna

Explanation:

The central dogma of molecular biology describes the flow of genetic information. DNA undergoes transcription to form RNA, and then RNA undergoes translation to form proteins. Option a is incorrect as the normal flow is not RNA to DNA first (except in retroviruses with reverse - transcriptase, but that's an exception). Option d is incorrect because DNA does not directly convert to protein without RNA as an intermediate. Option b correctly represents the general flow (DNA→RNA→Protein) for most organisms in the context of the central dogma.

Answer:

B. DNA → RNA → Protein
