.Microarrays allow researchers to perform simultaneous monitoring of the profiles of many gene expressions under diverse experimental environments. Furthermore, it is relied upon to establish the co-expressed genes in certain tissues or cells that are actively utilized in making proteins. Besides, the bioinformatics research largely depends on this technique to examine the gene expression. Additionally, it is evident that clustering of gene expression data is an important process that helps to identify co-expressed genes or the clusters of samples and genes which can be regarded as biological relevant
