ABSTRACT
The discovery of biomolecular sequences and exploring their roles, interplay, and common evolutionary history is fundamental to the study of molecular biology. Three types of sequences fill complementary roles in the cell: DNA sequences, RNA sequences, and protein sequences. DNA sequences are the basis of genetic material and act as the hereditary mechanism, providing the recipe for life. RNA sequences are derived from DNA sequences and play many roles in protein synthesis. Protein sequences carry out most essential processes such as tissue building, catalysis, oxygen transport, signaling, antibody defense, and transcription regulation. The first part of this book will describe the alignment algorithms used to compare these sequences.
