Mad2 dimerization is known to be critical for checkpoint signaling, and we made an R133A, Q134A double substitution in fission yeast Mad2p as a mad2 loss-of-function control allele for these experiments.
It believes that, while Bush sought too quickly to move to fast reactors, there is a need to double spending on nuclear fission research, currenly about $500 million.
This specialized process is likely to require a novel set of proteins that can facilitate the fusion and fission of double membranes, which is possibly unrelated to the conventional clathrin-mediated or caveolin-mediated processes.
Allow each group select a slip of paper or index card with the name of a scientific or technological breakthrough (nuclear fission, the double-helix, pesticides, the internal combustion engine, plastics, the silicon computer chip).
The two Y chromosomes in males (m and st) possibly arose from a double-strand break (or fission) in one proto-Y chromosome, followed perhaps by intrachromosomal rearrangements, such as pericentric inversions, in the larger element.
It had been reported that single-stranded DNA might be a better template than double-stranded DNA in fission yeast (Simon and Moore 1987) and that it can act as a HR template in mammalian cells (Fujioka et al. 1993).
This is, among other observations, suggested by the finding that, in cells of a dnm1 vps1 double-deletion strain, peroxisome fission is completely blocked, resulting in the presence of a single enlarged peroxisome per cell, even after prolonged cultivation under peroxisome-inducing conditions.
Apatite double dating (U-Pb and fission track) and thermal history modelling were applied to three late Eocene granitoid massifs within central and southern Sakhalin: the Aniva, Okhotsk and Langeri complexes.
Similarly, in fission yeast, rad3 tel1 double mutants are incapable of maintaining telomeres and generate survivors by creating circular chromosomes (Naito et al, 1998).
It determines fragment masses and kinetic energy distributions produced in nuclear fission by means of the double velocity and double energy (2v 2E) method.
