Researchers quantify more noise in gene expression
Human identical
twins have different fingerprints and march to the beat of subtly different phenotypes, an indication of heterogeneity which led bioengineering researchers at the University of California, San Diego (UCSD) to devised computer algorithms that identify the u...
