Question

Which of the options has correct identification of ‘P’, ‘Q’ and ‘R’ in the illustration of ‘Central Dogma’ given below?

विकल्प

• P – Replication, Q – rRNA, R – Transcription

• P – Translation, Q – mRNA, R – Transcription

• P – Replication, Q – mRNA, R – Translation

• P – Transcription, Q – mRNA, R – Translation

Answer 1

P – Transcription, Q – mRNA, R – Translation

Explanation:

DNA (deoxyribonucleic acid) is found in the nucleus of cells and holds an organism's genetic information. The information held in DNA is converted into messenger RNA (mRNA) through a process known as transcription. 

The genetic code is transported from the nucleus to the ribosomes in the cell's cytoplasm via mRNA. At the ribosomes, the genetic code is translated into a specific sequence of amino acids, which then make a protein. This procedure is known as translation. Thus, (P) denotes transcription, (Q) mRNA, and (R) protein.
