The presence of this intron in so many Syt genes could be interpreted as evidence that evolutionary alteration of this site is hazardous.
The evolutionary alteration of external exons in the 5'-UTR may be caused by the alternative usage of promoter sequences [ 38].
Whether and how the evolutionary alteration of Hsp70 expression and thermotolerance among the Stratiomyidae species involves changes to the hsp70 genes themselves remain unanswered questions.
The mode of evolutionary alteration of satellite DNA sequences may vary among different species, however.
DcAFP and grass LRR-IRI genes are therefore intriguing examples of parallel evolution of function by two completely different molecular mechanisms; evolutionary alterations of a pre-existing LRR-domain and evolution of a novel repeat domain with ice binding properties.
Thus, we hypothesised that an evolutionary alteration occurred in the anterior posterior (AP) patterning system of limb buds.
Transition/transversion (Ts Tv) biases observed in genome comparisons are potentially the result of mutational and/or selective evolutionary processes that influence the alteration of the two fundamental types of nitrogenous bases (i.e., purines and pyrimidines) that comprise DNA.
The nature of the evolutionary alterations that arise from regulatory changes depends on the hierarchical positions of these changes within a GRN.
The observed diversity of the proteome composition in organelles across different lineages points to the existence of evolutionary retargeting events, i.e. the alteration of the sub-cellular localization of a protein throughout evolution.
Morphological differences between polyp types can be attributed to simple changes in their axial patterning during development, and it has long been hypothesized that these specialized polyps arose through evolutionary alterations in oral-aboral patterning of the ancestral gastrozooid.
