Changing the DNA in living organisms to create
genetic engineering something new.
Genome The total DNA present in the nucleus of each cell
Restriction enzyme Bacterial enzyme that cuts the DNA at a specific code.
A process in which an electric current is used to separate
Gel electrophoresis DNA fragments according to the size of the fragments
A new generated DNA molecule produced when DNA is
Recombinant DNA combined from at least two organisms.
Small, circular, double- stranded DNA molecules that
occur naturally in bacteria and yeast cells—can be used
Plasmid as vectors because they can be cut with restriction
enzymes.
An enzyme joins the two DNA fragments chemically.
DNA ligase Normally used by cells in DNA repair and replication,
A process occurs when Some of the bacterial cells take
Transformation up the recombinant plasmid DNA.
Cloning Creation of identical copies of an organism
Identifies the DNA sequence of cloned recombinant DNA
DNA sequence molecules for further study.
Polymerase chain A technique can be used to make millions of copies of a
specific region of a DNA fragment by knowing the
reaction sequence of a DNA.
Transgenic Organisms genetically engineered by inserting a gene
organism from another organism.
A carrier transfers the recombinant DNA into a bacterial
vector cell called the host cell .the examples of the vectors are
plasmid and virus.
