Question

The diagram represents the 'central dogma' of molecular biology. Choose the correct combination of labeling.

• A. A - protein, B - RNA, C - DNA, D - translation, E - transcription
• B. A - RNA, B - DNA, C - protein, D - transcription, E - translation
• C. A - transcription, B - translation, C - protein, D - DNA, E - RNA
• D. A - DNA, B - RNA, C - protein, D - translation, E - transcription
• E. A - DNA, B - RNA,C - protein, D - transcription, E - translation

Answer 1

The correct option is E A - DNA, B - RNA,C - protein, D - transcription, E - translation

Central dogma represents the path of flow of genetic material, as proposed by Crick. It comprises three major processes; first is the copying of parental DNA (A) to form daughter DNA molecules with identical nucleotide sequences called as replication; the second is transcription (D) which is process by which parts of the genetic information encoded in DNA are copied precisely into RNA (B) and the final step is translation (E), whereby the genetic information encoded in mRNA is translated into a polypeptide/protein (C) with a particular sequence of amino acids. Correct answer is E.
