B4 Microarrays

The phenotype of a cell is determined by the amount, the proportion and the condition of proteins present in this cell. Although every cell in an organism possesses the same genetic information, only certain genes are transcribed into messenger ribonucleic acid (mRNA) according to the function and demands of the cell. Based on the information provided by the mRNA, the information is translated into the corresponding protein, contributing to a distinctive set of proteins for every cell and every status of the cell, defining its phenotype.
