To study random fluctuations in gene expression in this regulatory network, Raj et al. 2 used a fluorescence-based technique that detects single messenger RNA molecules in cells 5.

CHEVY CHASE, Maryland, July 29, 2005 -- Random fluctuations in gene expression can influence the fates of cells infected with human immunodeficiency virus (HIV) far more than previously thought ...

In diploid organisms, expression from only one allele is frequently observed. This Review focuses on the widespread random monoallelic expression (RME) of autosomal genes, highlighting both the ...

Spineless, the gene responsible for the expression of light-sensitive Rhodopsin proteins in flies, is expressed in two alternative ways in flies, but in three different ways in butterflies 1. “They ...
