One modern result of molecular biology is crops that are genetically modified organisms, or gmos. scientist produce gmo crops by taking a piece of dna coding for a certain gene from one organism and inserting it into the dna of another organism, called the host. the host expresses the new gene along with all of its other genes just as it normally would-by transcribing it to rna and translating it through protein synthesis. this process gives the host organism a new gene and thus a trait, such as pest resistance, that its species naturally does not carry in its genome. what must be true for a genetically modified organism to be able to express a gene it has received from another species?
