Climate of the Arctic continuously, with 30 stations in the Arctic from 1950 to 1991. These stations collected data that are valuable to this day for understanding the climate of the Arctic Basin. shows the location of Arctic research facilities during the mid-1970s and the tracks of drifting stations between 1958 and 1975. Another benefit from the Cold War was the acquisition of observations from United States and Soviet naval voyages into the Arctic. In 1958 an American nuclear submarine, the "Nautilus" was the first ship to reach the North Pole. In the decades that followed submarines regularly roamed under the Arctic sea ice,
Nuclear cap-binding protein complex Nuclear cap-binding protein complex Nuclear cap-binding protein complex is a RNA-binding protein which binds to the 5' cap of pre-mRNA. The cap and nuclear cap-binding protein have many functions in mRNA biogenesis including splicing, 3'-end formation by stabilizing the interaction of the 3'-end processing machinery, nuclear export and protection of the transcripts from nuclease degradation. When RNA is exported to the cytoplasm the nuclear cap-binding protein complex is replaced by cytoplasmic cap binding complex. The nuclear cap-binding complex is a functional heterodimer and composed of Cbc1/Cbc2 in yeast and CBC20/CBC80 in multicellular eukaryotes. Human nuclear cap-binding protein complex shows the
