nucleotides in DNA or RNA that determines
the specific amino acid sequence in the
synthesis of proteins.


It is possible to move material between
species because the genetic code is universal.
The transfer of genetic code can cause
genetic mutations in animals

Gene transfer: Involves the use of plasmids,
host cell (bacterium, yeast, or other cell),
restriction enzymes (endonucleases), DNA ligase.
Gene therapy: The treatment of certain
diseases by introducing specific engineered genes
in a patients cells.
Vector: Is what is needed to carry the gene into
the host cell; plasmids are often used as vectors.
Restriction enzyme: Used to cut a desired
section of the DNA.
Plasmids: Used to clone a desired gene.
Host cell: The cell used to receive the genetic
material.

A human gene that codes for insulin can be
inserted into a plasmid and then inserted into
a host cell (bacterium). The bacterium then
synthesis insulin which can then be collected
and used by diabetics.
◦ Note- Gene transfer involves the following
elements: a vector, a host cell, restriction enzyme,
DNA ligase.

Step 1: Introduce the desired gene into a
plasmid and transfer it into a bacterial cell,
then culture the bacteria.
◦ Note: many of the bacteria will have a plasmid with
the desired gene

Step 2: Use restriction enzymes to cut the
desired gene out of the plasmids and purify
the gene using gel electrophoresis.
