★ AQA A Level Biology Specification Reference: - 184.108.40.206 Recombinant DNA technology (A-level only). Recombinant DNA technology involves the transfer of fragments of DNA from one organism, or species, to another. Since the genetic code is universal, as are transcription and translation mechanisms, the transferred DNA can be translated within cells of the recipient (transgenic) organism. Interpret information relating to the use of recombinant DNA technology.
★ CIE A Level Biology Specification Reference: - 19.1 Principles of genetic Technology: a) define the term recombinant DNA. b) explain that genetic engineering involves the extraction of genes from one organism, or the synthesis of genes, in order to place them in another organism (of the same or another species) such that the receiving organism expresses the gene product.
