Yet in an experiment at the National Institutes of Health a decade ago, men kept on a schedule of 10 hours of light and 14 hours of darkness — mimicking the duration of day and night during winter — fell into the same, segmented pattern.
Mutants in these genes lack either the anterior or posterior part of the segmented pattern.
The segmented pattern of the Drosophila embryo is organized by two activities localized at the anterior and posterior egg poles.
They are often arranged in continuous or segmented pattern along the lines where serious snow or sand deposition occurs, following a principle that line and wind direction are orthogonal to prevent disasters [16, 17].
The functional outcome of the developmental processes we describe is the segmented pattern of denticle bands.
Peroxisomal marker proteins were detectable in a segmented pattern on such elongated peroxisomes, like beads on string, with constriction of the membrane (Grabenbauer et al., 2000; Koch et al., 2004; Itoyama et al., 2012; Itoyama et al., 2013).
