The Method of Loci has been used since ancient times to memorize important information.
The NE-PER Nuclear and Cytoplasmic Extraction Reagent Kit is a reagent-based protocol that enables the stepwise lysis of cells, separation of the cytoplasm from the intact nuclei and then extraction of nuclear proteins away from genomic DNA and mRNA.
Nuclear reactors use a type of nuclear reaction called nuclear fission. Another type of nuclear reaction-nuclear fusion-happens in the Sun and other stars.plitting atoms. Fission is another word for splitting. The process of splitting a nucleus is called nuclear fission. Uranium or plutonium isotopes are normally used as the fuel in nuclear reactors, because their atoms have relatively large nuclei that are easy to split, especially when hit by neutrons.
