The spare, precise language imprints on the mind with the clarity of a snapshot.
Those sources of influence themselves were sufficiently diffuse that it is difficult to make precise Gassendi's imprint on these later authors, except where they explicitly acknowledge their debts.
Five weeks later, their claim was put beyond doubt by a second paper, in which Crick explained in detail how genes need to employ only sequences of the main bases in matched pairs to specify, by positive and negative imprint, the precise and unique amino acid sequence of any protein, whatever its complexity.
You have probably never heard of steppers, for instance, but they are the super-precise optics-based machines that imprint microscopically fine lines on computer chips and LCD displays.
Recent studies have focused on mechanisms in ES cell models [ 4, 8, 13], but the precise timing and mechanisms responsible for imprinting at Igf2r/Airn in vivo remain unknown.
The precise estimation of three-way interactions of imprinting effects between different generations requires a large sample size (2000 in total) and large heritability (0.4).
The precise functions and mechanisms associated with placenta-specific imprinting of DNMT1 and AIM1 remain to be investigated.
Interestingly, they are generally not imprinted in all tissues, and the imprinted pattern can be limited to a precise developmental stage.
Molecular imprinting is an emerging field that produces precise chemical architecture that can bind analytes and differentiate between similar molecules with enantiomeric resolution.
In addition, imprinted genes having a restricted expression profile, either spatially or temporally, or with an imprinted pattern limited to a precise developmental stage, organ, or isoform, are probably very difficult to identify, particularly in humans.
