Genomics - Study of the entire genome of an organism. It enables the primary sequence of a protein to be identified easily from small amounts of sequence data.
Proteomics - Study of quantity & quality of all expressed protein.
Glycomics - Study of structure & function of chains of sugar.
Cytogenetics - It is a branch of genetics which deals with the structure & function of the cell, especially the chromosome.
Pharmacogenomics - Study of genetically determined variation in responses to drugs in human or in laboratory organisms.
