An international team of mathematicians has proposed a new solution to understanding a biological puzzle that has confounded molecular biologists.
They have applied a mathematical model to work out the functioning of small molecules known as microRNAs – components of the body akin to the electronics in modern airplanes.
For a long time molecular biologists thought that the major role of RNA in living cells was to serve as a copy of a gene and a template for producing proteins, major cell building blocks. This belief had been changed at the end of 90s when it was found that myriads of RNA molecules are involved in regulating speeds of practically all molecular mechanisms in a cell. These abundant molecules are essential in regulating the speed of protein production– a vital function in bodily processes, including development, differentiation and cancer.
