A unique nucleus-directing domain, added at the invertebrate-to-vertebrate transition, confers this novel non-translational activity of SerRS.
The "pedestrian cities", characterized by a unique compact nucleus, have been developed until the middle of the XIX century in Europe; afterwards there is a shift toward building small centres localized along the main railway systems ("transit oriented cities").
In adult A. acetabulum, growth and morphogenesis occurs almost exclusively at the stalk apex, centimeters away from the unique nucleus located in the rhizoid.
The recent observation that active OR genes (but not inactive OR genes) interact with a unique locus in the nucleus [ 20], termed the "H region", that was previously characterized as having strong enhancement activity [ 18], is consistent with this model.
The nuclear periphery is a unique subcompartment of the nucleus that consists of the inner nuclear membrane (INM) and its associated proteins, nuclear lamina (NL) and chromatin [ 1, 2].
In either case, the chloroplast genome of Klebsormidium is unusual in lacking the 5S rRNA gene, 4.5S-homologous region, and six ribosomal protein genes typically present in streptophyte chloroplast genomes and displays a unique dependency on the nucleus for chloroplast protein synthesis.
To exclude from the analysis events corresponding to more than one nucleus, successful segregation of each nucleus as a unique ROI was conducted using an open pre-processing filter combined with a watershed erosion algorithm.
However, DNase 1L2-deficient mice have a unique phenotype, with undigested nuclei being present only in hair shaft and nail plate.
We computed protein features from the autofluorescence-removed images to assign a unique sub-cellular compartment (nuclei, membrane or cytoplasm) to each detected pixel, as described (Ginty et al., 2008).
In the 2d clone, the six latest-born nuclei form a unique pattern consisting of three laeotropically skewed columns; as development proceeds, the lower-left nucleus in this array (2d122) tends to be displaced away from its sister toward the vegetal pole (Figures 14, 16 21).
Unlike protein-coding mRNAs, the Gomafu RNA escapes nuclear export and stably accumulates in the nucleus, making a unique nuclear compartment.
