MicroRNAs are as RNA molecules which are smaller in size and are present in the genomes of plants and animals. It is evident that these microRNAs play an important role in the differentiation of cells and their growth, their movement, and in programmed cell death (apoptosis).
The length of these miRNAs is about 22 nucleotides long and they tend to regulate the gene expression when are bound to the specific mRNAs. miRNAs are responsible for silencing the genes present on other loci but do not silence those loci on which they are present. The analysis of miRNA expression can inform us regarding cancer, CVD, certain metabolic diseases, and dysregulation in the immune system.
