DNA Technology

Definitions Genetic engineering - process of altering genes to combining DNA from two or more organisms. Genetic engineering - process of altering genes to combining DNA from two or more organisms. Recombinant DNA - product of genetic engineering. (contains at least two organisms’ DNA) Recombinant DNA - product of genetic engineering. (contains at least two organisms’ DNA)

Steps in Producing recombinant DNA: 1. Restriction enzymes are used to cut DNA into small pieces at specific locations. 2. Small DNA pieces are spliced with a sequence of bacterial DNA called a PLASMID. 3. The resulting plasmid is inserting into a bacteria cell. 4. The bacteria cell divides producing new copies of the recombinant human/bacteria DNA.

Human Genome Project Ongoing project to sequence all the base pairs in human DNA so we can determine what sections of DNA code for what traits. Ongoing project to sequence all the base pairs in human DNA so we can determine what sections of DNA code for what traits.
