Microsoft PowerPoint - Biotechnology and Genetic Engineeringvary between individuals and thus can be used
to identify an individual.
Polymerase Chain Reaction (PCR)
– The DNA is then cut into fragments using restriction enzymes.
– Restriction enzymes recognize and cut specific nucleotide sequences.
DNA Identification

called recombinant DNA.
– The fragments are separated by size using gel
electrophoresis.
