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.
If genetic material from another species is added to the host, the resulting organism is called transgenic. If genetic material from the same species or a species that can naturally breed with the host is used the resulting organism is called cisgenic. Genetic engineering can also be used to remove genetic material from the target organism, creating a gene knockout organism. In Europe genetic modification is synonymous with genetic engineering while within the United States of America it can also refer to conventional breeding methods.
