KEY TERMS HAND OUT



Applications of reproductive technology:

-

Production of plants that are resistant to disease, can also be cloned and produce thousands

-

Through artificial
insemination farmers can generate hundreds of offspring, can also freeze
sperm or fertilized egg and transport

-

Build up species that are endangered. Also can study hormones of insects and animals

-

Help infertile women become pregnant

-

Cloning can be done by

inserting a nucleus from a parent organism ‘s cell into the egg cell from
which the nucleus has been removed, resulting in an egg with 100 % of its genetic information
from that single parent . (Mammals implantation would occur inside the body of the fe
male)


Uses of gene manipulation:

-

Produce plants with beneficial traits

-

Bacteria that cleans up oil spills, or produce human growth hormones

-

Forensics
-

copy and recognizing DNA from smallest drop of blood

-

Gene splicing, an example human insulin
-
>into bact
eria
-
>offspring that produce insulin


Process of genetic engineering:

-

Removal of a desirable gene from a cell and adding it to the gene structure of a bacterial cell.
This becomes the RECOMBINANT DNA, which gets placed into the bacteria cell. This bacter
ia
then has the capability to produce the protein produced by the original cell.

-

Restriction enzymes are enzymes capable of snipping DNA molecules at particular nitrogenous
base sequences. This enables the alteration of DNA which results in the cells bein
g genetically
engineered.
