Question

Central dogma in molecular biology states that the genetic information flows from:

• A. RNA $\to$ Proteins $\to$ DNA
• B. proteins $\to$ RNA $\to$ DNA
• C. RNA $\to$ DNA $\to$ Proteins
• D. DNA $\to$ RNA $\to$ Proteins

Answer 1

The correct option is D DNA $\to$ RNA $\to$ Proteins

Francis Crick proposed the Central dogma in molecular biology.

Central dogma in molecular biology states that the genetic information flows from DNA $\to$ RNA $\to$ proteins.

It is defined as a process in which the information in DNA is converted into a functional product (protein).

It is suggested that the information present in DNA is essential to synthesise all proteins and mRNA acts as a messenger that carries information through the ribosomes.

The genetic information is copied from one strand of the DNA into mRNA and this process is called transcription. Transcription is followed by translation.

Translation is the process by which the protein is synthesised from the information contained in the messenger RNA (mRNA).
