Method |
"[Researchers] designed an experimental system to visualize
and quantify the rate of spontaneous errors in gene expression at
a single-cell level in living Bacillus subtilis cells. [Their] strategy was to
introduce mutations into the ORF of a chromosomally encoded
gfp reporter allele, such that errors in protein production would
yield functional GFP molecules, visible by fluorescence microscopy." |
Comments |
(pp.11544-5:)"[Researchers] estimated the average amount of errors that occur during exponential
growth. The GFP signal emanating from the gfpfs [frame shift] and
gfpns [nonsense] mutant strains was quantified, averaged, and expressed as
a percentage of the GFP signal detected in gfpwt cells...Strikingly, the gfpfs cells contained 2.4±0.4% GFP molecules, whereas gfpns contained 0.4±0.1%
fluorescent protein molecules relative to gfpwt cells." |
