Summary Introduction

Introduction:

The genetic information in the cell consists of DNA and RNA . The process of transcription generates mRNA which gets translated to form proteins inside the cell. Thus, the genetic information is transferred from the nucleotides to the proteins inside the cell.

The proteins take part in the metabolic functions by catalyzing the reactions which are essential for the cell. These scientific observations are part of the RNA -first hypothesis which explains the formation of the nucleotides molecules and proteins inside the cell. It was proposed by Thomas Cech and Sidney Altman, who proposed that the RNA molecules act as self-catalytic molecules.
