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 power stations use the heat released by nuclear reactions to boil water to make steam. The type of nuclear reaction used is called nuclear fission. In nuclear fission: 1  A neutron collides with a uranium nucleus. 2  A uranium nucleus is large and unstable. 3  The uranium nucleus splits into two similar-sized smaller nuclei. 4  More neutrons are released. 5  These neutrons can then collide with more uranium nuclei.
