INTRODUCTION

The Human Genome Project revolutionized scientific research in the field of molecular biology. Many of the techniques and gene interaction knowledge base currently in use are the result of the project. The cost and time to conduct such studies continues to decrease, resulting in the generation of information relevant to the formulations chemist. Molecular cell biology investigates how cells develop, operate, communicate, and control their activities. Cells communicate with body tissue, which is composed of cells. Tissues communicate with other tissues and organs throughout the body. Generally the transfer of information between cells, tissues, and organs is through proteins. We now know that genes consisting of deoxyribonucleic acid (DNA) are responsible for biological structure, maintenance, and integration of cellular function. DNA indirectly controls the synthesis of many small molecules including proteins. DNA may be considered a storage form of genetic information. Gene expression is how cells “know” to make the right proteins at the right time in the right quantities.
