Recombinant paper plasmids lab some of the most important techniques used in biotechnology today involve from parts taken from more than one source. your genome is recombinant in that part of it came from your mother and part came from your father. recombinant dna molecules are pieces of dna that have been reassembled from places taken from more than one source of dna. a gene coding for particular protein is transferred into a host organism. the host multiplies, and produces the desired protein insulin has been inserted into the common bacterium, e. coll. often, one of these making recombinant dna molecules. a recombinant object has been reassembled in volume. for example, the gene that codes for the production of human dna sources is a plasmid a plasmid is a small, circular dna molecule that can reside in cells, particularly bacteria. the cell's dna replication them because
