A method for fine mapping quantitative trait loci in outbred animal stocks.

abstract：:Inhibition of protein synthesis in rabbit reticulocyte lysates by double-stranded RNA is caused by the inactivation of IF-3, an initiation factor required for the recycling of ribosomes and for their binding to messenger RNA. The evidence for this is that (i) the inhibition can be overcome by addition of exogenous If-...
