Summary Introduction

To describe: The splicing reaction for pre-mRNA.

Introduction: To convert genotype to phenotype, the conversion of information saved in the DNA to proteins is required. The DNA strand is composed of pyrimidines (cytosine, C, or thymine, T) and purines (guanine, G, or adenine, A). Thymine pairs with adenine through two hydrogen bonds and forms the A-T base-pair. Cytosine pairs with guanine through three hydrogen bonds and forms the G-C base-pair.  In the RNA sequence, one of the pyrimidines called thymine is replaced by uracil U.
