Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.
Undulatory animals moving on the surface must manage material memory by either having a slender anatomy that facilitates avoiding previously remodeled substrate, or using waveshapes that effectively utilize the memory.
Distinct lateral inhibitory circuits affect spiking in olfactory bulb mitral and tufted cells differently, which ultimately allows each cell type to best discriminate between similar odors in separate concentration ranges.
Rates of germline mutation accumulation are highly variable across families of similar genetic ancestry, and post-zygotic mosaicism is a substantial source of de novo mutations.
Growing upwards in the young seedling is controlled by two cooperative mechanical mechanisms: cellulose orientation in inner tissues and differential elasticity in epidermal cells.
A comprehensive genome scan of 18,000 multi-ethnic individuals with 3-dimensional facial images highlighted multiple face-associated genetic loci for which regulatory activities in human neural cells were established.
