Inbreeding | breeding individuals with similar traits together |
Hybridization | breeding individuals with different traits together |
Artificial Selection | another name for selective breeding |
Recombinant DNA (rDNA) | DNA from two different organisms spliced together |
Plasmid | a circular DNA molecule in bacteria; used in genetic engineering |
4 steps of genetic engineering | 1. find the gene you want and cut it out 2. Gene splicing 3. Insert rDNA into bacterium 4. Clone bacteria and collect the products |
Restriction Enzyme | enzyme that cuts DNA at specific sequences |
Transgenic | containing genes from other species |
DNA Fingerprinting/DNA Profiling | analysis of DNA fragements as a form of identification |
Gel electrophoresis | a laboratory method used to separate mixtures of DNA according to size |
Cloning | making a genetically identical copy of DNA or of an organism |
Somatic Cell Nuclear Transfer | moving a cell nucleus and its genetic material from one cell to another |
The force that causes DNA to move during electrophoresis | electricity |
