entities are objects outside the system‚ with which the system communicates. External entities are sources and destinations of the system’s inputs and outputs. 1.b) ENTITY RELATIONSHIP DIAGRAM Entity–relationship model (ER model) in software engineering is an abstract way to describe a database. This article refers to the techniques proposed in Peter Chen’s 1976 paper.An ER model is an abstract way to describe a database. There are three basic elements in ER models: Entities are the "things"

AmirAshkan Semyary By using the techniques of genetic engineering scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell. It is necessary to obtain a gene to modify genetic material. First a scientist isolates plasmid DNA from bacteria and DNA carrying a gene of interest from cells of another organism‚ such as an animal. A piece of DNA containing the gene is inserted into a plasmid‚ producing recombinant DNA
