Nestling begging calls extract care from parents but expose them to eavesdropping by predators, which selects for cryptic signal design.
Reaching the unmarked door, I knocked the cryptic signal.
Consequently, we chose an individual-tumor alternative to a global threshold for alteration, the former being more sensitive to the detection of this sort of cryptic signal.
Whether semiotically wised up, sincerely romantic or both, artists like Ed Ruscha, Philip Taaffe, Martin Puryear and Dana Schutz, among countless others, continue to send out cryptic signals, perhaps in hope of getting a reassuring answer from the universal mind, if there is such a thing.
As an extension to the already known tandem signals like in the nicastrin or CYP2E1 precursors [41], [43], our NtraC model provides a framework for cryptic signals.
Similar observations have been made for other proteins containing consecutive "tandem" signals rather than "cryptic" signals as described by the NtraC model.
Finally, several modes of natural selection could operate over regulatory regions that would result in a rapid turnover of functional binding sites and maintenance of numerous cryptic signals, such as compensatory selection, stabilizing selection or selection for robustness to mutation.
Our results bring into question the prevalence, evolutionary conservation, and antiquity of internal or cryptic signals in proteins targeted to mitochondrial organelles.
Conspicuous coloration already carries a significant detectability cost, although this can potentially be offset by predators learning to associate conspicuous coloration with toxicity more quickly with conspicuous compared to cryptic signals (e.g. Gittleman & Harvey 1980; Alatalo & Mappes 1996; Lindström et al. 1999).
As such, small-scale mutations may either disrupt splicing signals or create cryptic splicing signals, leading to changes in splicing patterns, converting formerly intronic sequence into exonic sequence or vice versa [ 19- 22].
Evidence for aberrant V(D J rearrangements in 73-deficient thymocytes was obtained by assaying for internal deletion at the Bcl11b and Notch1 loci, which both contain cryptic recombination signal sequences (RSS) that are accessible to Rag, and are frequently mutated in T cell lymphomas [28] [30].
