Concept introduction:
The term DNA stands for deoxyribonucleic acid. Deoxyribonucleic acid is the most important biomolecule that stores genetic information of a living organism. In other words, DNA is the blueprint of all organisms. The DNA first synthesizes RNA by the process of transcription and then the RNA synthesizes the proteins by the process of translation.
