Topic 21 recombinant dna tech / topic 22 cloning your fav gene (yfg) Celestial collision recombinant dna technologies cant fix this. Nuclear catastrophe recombinant dna technologies cant fix this. Global warming recombinant dna technologies can work to fix this. Definition: the techniques which recombine dna fragments from diff sources into new molecules wit unique features. Engineering biological systems, with the goal of carrying out novel functions or performing existing functions more efficiently. Manipulating genomes of organism is not new. Humans been doing it foe 1000sof years though classical genetic selection. Plant/crop and livestock breeding are examples of humans manipulating the dna of other organisms. Classical genetics: slow: limited by the breeding time of the organism and chance genetics events, exchange of genetic materials is limited to breeding species. Recombinant dna tech: rapid: as quick as a few days in some organisms, no limitations. Research key to understand cell and molecular structure/function.
