Term
DNA fingerprints
Definition
sctions of DNA which are unique to the person or organism they came from
Term
gene cloning
Definition
the DNA technology in which a gene is isolated, then copied exaclty many times over. 
Term
gene therapy
Definition
a treatment where a person born with a defective gene is given the proper gene through recombinant therapy
Term
ligase
Definition
an enzyme which is able to base-pair segments of DNA
Term
plasmids
Definition
natually occuring (and now man-made too) segments of DNA that are taken up by bacteria and remain in bacteria indefinitely
Term

polymerase chain reaction

(PCR)

Definition
a method of amplifying a small sample of DNA
Term
probe
Definition
short segments of DNA that will stick to specific areas of of single-stranded DNA
Term
recombinant DNA
Definition
a DNA molecule that is made up of DNA derived from two or more organisms
Term
recombinant plasmid
Definition
a plasmid made from two or more sources of DNA (one of the sources being the initial plasmid DNA)
Term
restriction enzyme
Definition
enzymes normally found in bacteria which cut foriegn DNA entering the cell
Term

restiction fragent length polymerase

(RFLP)

Definition
a process to cut large pieces of DNA into smaller pieces for DNA fingerprinting
Term
restiction fragments
Definition
DNA segments obtained through RFLP
Term
reverse transcriptase
Definition
an enzyme which synthesizes DNA from an mRNA template
Term
selective breeding
Definition
a process by which organisms containing a particular trait or traits are bred with one another across may generations to refine the desired trait. the oldest form of genetic engineering
Term
sticky ends
Definition
the double-stranded end of a cut DNA with a short length of single-strand material hanging off of it
Term
transformation
Definition
the process of changing a trait in an organism as a result of the introduction of recombinant DNA into that organism
Term
transgenic
Definition
an organism that has DNA in it from another species
Term
viruse
Definition
a particle which contains DNA ot RNA, but is not a living organism
