Chapter 23, Problem 1MTE

Summary Introduction

To explain: Why the molecules such as base, ribose, and phosphate spontaneously assembled to form the first nucleotides.

Concept introduction:

The nitrogenous bases were present during the prebiotic earth that formed the RNA molecule. RNA molecule is diverse in functions. It is not confined to its role as genetic material in certain viruses but also has catalytic activity. Its diverse role might have originated during the pre-cellular times.

Summary Introduction

To explain: Why it is more likely that such compounds arose from the combination of two molecules that were half-base and half-ribose.

Concept introduction:

The nitrogenous bases were present during prebiotic earth that formed the RNA molecule. RNA molecule is diverse in functions. It is not confined to its role as genetic material in certain viruses but also has catalytic activity. Its diverse role might have originated during the pre-cellular times.
