MCQ (Single Correct) +4 −1

The central dogma of molecular biology states that

DNAis transcribed into RNA, which is translated into proteins Correct Proteins are transcribed into RNA, which is reverse-translated into DNA DNA directly produces proteins in a cell Only RNA is involved in gene expression

Central Dogma of Molecular Biology:
Articulated by Francis Crick (1958, 1970), the central dogma describes the sequential flow of detailed genetic information within a biological system:

$$\text{DNA} \xrightarrow{\text{Transcription}} \text{RNA} \xrightarrow{\text{Translation}} \text{Protein}$$

Genetic information stored in DNA is transcribed into messenger RNA (mRNA) by RNA polymerase, which is subsequently translated into polypeptides/proteins by ribosomes.
Conclusion: DNA is transcribed into RNA, which is translated into proteins (Option 1).

Correct option: (1) DNAis transcribed into RNA, which is translated into proteins
