Question

Name the scientist who proposed the central dogma in molecular biology. Give its schematic representation.

Hint:

Francis Crick proposed the central dogma, which is DNA to RNA to protein.

Answer 1

Step 1: Name the scientist:
The central dogma was proposed by Francis Crick.

Step 2: State the idea:
The central dogma says that genetic information flows from DNA to RNA and then to protein.
DNA is copied into mRNA by transcription. The mRNA is read by ribosomes to make a protein by translation.

Step 3: Schematic representation:
\[ \mathrm{DNA} \xrightarrow{\text{transcription}} \mathrm{RNA} \xrightarrow{\text{translation}} \mathrm{Protein} \]
DNA can also copy itself by replication.

Final Answer:
Francis Crick proposed it: DNA to RNA to protein.
