Proteasome
Proteasomes are large protein complex es inside all eukaryote s and archaea , as well as in some bacteria . In eukaryotes, they are located in the nucleus and the cytoplasm .Peters JM, Franke WW, Kleinschmidt JA. (1994) Distinct 19S and 20S subcomplexes of the 26S proteasome and their more
RNA interference trims double stranded RNA, to form small interfering RNA or microRNA . These processed RNAs are incorporated into the RNA-induced silencing complex (RISC), which targets messenger RNA to prevent translation .
RNA interference (RNAi) is a mechanism that inhibits gene expression more
Xenon
Xenon ( in the UK, in the US) is a chemical element that has the symbol Xe and atomic number 54. A colorless, heavy, odorless noble gas , xenon occurs in the earth's atmosphere in trace amounts. Although generally unreactive, xenon can undergo a few chemical reaction s such as the forma more
Tooth development
Tooth development is the complex process by which teeth form from embryo nic cells , grow , and erupt into the mouth . Although many diverse species have teeth, non-human tooth development is largely the same as in humans. For human teeth to have a healthy oral environment, more
Metabolism adenosine triphosphate , a central intermediate in energy metabolism.
Metabolism is the set of chemical reaction s that occur in living organism s in order to maintain life . These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environme more
