Bioinformatics as an integrated field of science concentrated on different aspects of life from protein to DNA and RNA. Because of million protein sequence records in protein databases all around the world bioinformatics need to classify and study it collectively to understand it and process it in large data mining processes.
The proteome is a complex system involved in every human function. Researching proteomics helps us understand health and disease. Because proteins are the actual “doers” of the cell, they can teach us far more than genes. They are also far more difficult to study. So they study collectively in bioinformatics projects and research.
