Caesarâs father-in-law, Lucius Cornelius Cinna (d. 84 B.C.), had been a rival of Sulla. As a result, Sulla ordered Caesar to divorce Cornelia, but Caesar refused. Knowing such defiance could cost him his life, Caesar fled Rome and became a fugitive.
A transgenic organism is an organism which has been modified with genetic material from another species. The genetic modification is accomplished by inserting DNA into an embryo with the assistance of a virus, a plasmid, or a gene gun.
Modern genetic technology can be used to modify the genomes of living organisms. This process is also known as âgenetic engineering.â Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Most transgenic organisms are generated in the laboratory for research purposes. For example, âknock-outâ mice are transgenic mice that have a particular gene of interest disabled.
