there emerged a model for structure-dependent meiotic strand pairing, initiated by stem-loops extruded from duplex DNA helices. Stem-loop patterns were sensitive to small single base differences (DNA "accent" differences
Our findings highlight multiple lines of evidence suggesting that natural selection, due to both purifying and positive selection, has widely shaped patterns of nucleotide polymorphism at linked neutral sites in all three species. Differences in effective population sizes and rates of recombination ...
Glycolytic enzymes, which are active as tetramers, occur as 1–4 copies in vertebrate genomes, likely as a result of ancient genome duplication events (1R and 2R). They display clearly different evolutionary patterns (Figure 2). The tree for PFK reflects a perfect 1R/2R topology with three...
We used host age as a measure of host quality (from 9-to 16-day-old hosts), changed the number of ovipositing females to control the level of local mate competition (1 female and 10 females), and examined oviposition patterns of the wasps. The offspring sex ratios (proportion of females...
While studies on genomic adaptation tend to focus on the former, less is known about the genomic targets of natural selection in the latter situation. In this study, we investigate genomic adaptation in populations of the three‐spined stickleback Gasterosteus aculeatus L. across a small‐scale ...
Additional experiments determined (1) that the 25-m2plot size is the appropriate scale for investigation of patterns of fertilization in S. franciscanus, the species with the largest contiguous populations; (2) that S. purpuratus, the species commonly found in the intertidal and subtidal zones, ...
2). An in-depth analysis of temporal patterns of B. distachyon metabolites distinct between these timepoints revealed a variety of temporal behaviors, from linear, exponential or logarithmic increases to bell-shaped dynamics (Supplementary Fig. 3). Most compound intensities increased over time. ...
Together, these patterns of distribution repeated many previous observations, which have reported the involvement of occipital, occipitotemporal, parietal as well as frontal areas, in category processing following similar temporal dynamics1,25,55. However, as explained earlier, their reported category ...
Three-Dimensional Reconstruction is the process of creating 3-D anatomical images or models from sectioned material, allowing the study of complex morphologies by displaying objects in various orientations with volumes and surface areas determined. AI generated definition based on: Computer Methods and ...
