The RAV family number in cabbage (13) was larger than that in other plant groups, including Arabidopsis (6), rice (4), and tomato (3), but lesser than that of B. rapa (14). Cabbage contained more A ...

Sequence comparisons indicated that the common PvuU fragment was internal to the rRNA operons, specifically it contained the 5' end of the 23S rRNA gene. Regions flanking the PvuU fragment were then isolated from the co ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
