What is a restriction enzyme? an enzyme that CUTS sugar -phosphate bonds in the DNA backbone at specific points within particular nucleotide sequences in DNA TERM 2 What cuts up DNA into tiny fragments? DEFINITION 2 Restriction Enzymes TERM 3 What is the FIRST STEP a scientist takes to produce genetically engineered bacteria that makes a human protein? DEFINITION 3 Using resrtiction enzyme to cut out the genes from human DNA TERM 4 What is recombinant DNA? DEFINITION 4 It combines genes from DIFFERENT SOURCES or species into a SINGLE DNA molecule TERM 5 What is a plasmid? DEFINITION 5 small circular DNA molecule, separate from the much larger bacterial chromosome.
What are plasmids used for? Cloning TERM 7 What is used to cut DNA? DEFINITION 7 Restriction enzyme TERM 8 What is a genetic modified organism? DEFINITION 8 a organism that has acquired one or more genes by ARTIFICIAL MEANS -*Transgenic TERM 9 What is the genetically modified organism called if the source of the new genetic material is a different species? DEFINITION 9 Transgenic TERM 10 What happens during genetic modification? DEFINITION 10 a cell takes in DNA from ANOTHER source
If two DNA samples showed identical pattern and thickness of bands produced by gel electrophoresis , than the samples are? Have the same DNA, the fragments are the same size, and have the same DNA molecules TERM 17 What is the advantage of using genetically engineered bacteria to produce human proteins? DEFINITION 17 You can mass produce pure human proteins TERM 18 What are two situations that DNA fingerprints are useful? DEFINITION 18 Crime scenes, paternity, or genetic disease
