Summary Introduction

Introduction: Ribonucleic acid (RNA) is single stranded, and it consists of four nitrogenous bases, such as adenine, cytosine, guanine, and uracil. RNA was the first hereditary material. It was found that RNA can cause chemical reactions and also carry information, and this indicates that RNA was the first self-replicating molecule in the Earth’s history.
