This instrument is used for which process?
Making copies of DNA
Cloning
Gel Electrophoresis
Enhancing DNA
What is Gel Electrophoresis?
Is the process of producing genetically identical individuals of an organism either naturally or artificially.
Is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size.
Is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies.
________________ is a method widely used in molecular biology to rapidly make millions to billions of copies of a specific DNA sample allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail.
PCR
GMO
DNA
RNA
________________ is a molecule formed by splicing fragments of DNA from a different source or from another part of the same source, and then introduced into the recipient (host) cell.
DNA Polymerase
Recombinant DNA

Much of genetic engineering uses plasmids, which are:
Segments of RNA that must be attached to DNA before the DNA can replicate.
Small circlets of DNA found in bacteria.
Repeating sequences that protect DNA from digestion when it is inserted into a foreign cell.
Ends of cut DNA molecules that are sticky because they have unpaired base sequences.
The process by which pieces of DNA are transfered from one organism to another.
Gene Therapy
Genetic Engineering
Chromosomal Mutation
Bitotechnology
What is the function of plasmids in genetic engineering?
