Summary Introduction

To determine:

The reason behind the occurrence of more termination codons (UAA, UAG, and UGA) than the initiation codons.

Introduction:

The genetic code consists of a triplet code, in which three nucleotides encode a single amino acid in a protein. The genetic code has sixty-one codons that specify the twenty amino acids. The three codons are stop codons or nonsense codons that do not encode any amino acid. AUG is usually the initiation codon that encodes the amino acid methionine.
