Different levels of gene expression give each cell its specific characteristics and function through the production of different proteins. (hubrecht.eu)
In principle, Gage says, this process could generate distinct neural circuitry in each individual by altering the proportion of neuron types or levels of gene expression in the brain. (sciencemag.org)
Random fluctuations in transcription are unavoidable and a general aspect of life at the single - cell level and lead to «noise» around the average level of gene expression. (gladstone.org)
