INTRODUCTION

Foreign DNA(gene) is introduced into the animal,

using recombinant DNA technology.

Deoxyribonucleic acid (DNA) is unit of genetic

which is responsible of all quality and quantity

animal characters.

DNA coiled and coiled with histone protein to

produce chromosome .

EXTRACTION DESIRE GENE

For extraction of specific gene from of millions of

gene we need to Polymerase Chain Reaction

(PCR) technique and include:

DNA extraction

Thermo cycle device

Gene primer

Some chemical materials

METHODS OF TRANSGENIC ANIMAL

1- Retroviral Vector Method

2- Sperm Mediated Gene Transfer

3- Microinjection Method

4- Embryonic Stem Cell

1- RETROVIRAL VECTOR METHOD

when the virus vectors infect a host cell, the viral RNA is reverse transcribed in the cytoplasm making linear double-stranded DNA.

A retrovirus is a virus that carries its genetic material in the form of RNA rather than DNA.

In this method, retroviruses are used as vectors to transfer genetic material into the host cell

Infecting mouse embryo with a retrovirus which carry the new gene. 6

3- MICROINJECTION METHOD

1) transfer of a desired gene construct (of a single

gene or a combination of genes that are

recombined and then cloned) from another member

of the same species or from a different species into

the pronucleus of a reproductive cell;

2) in vitro culture of the manipulated cells to

develop to a specific embryonic phase; and

3) then transfer of the embryonic cells to the

recipient female.9

APPLICATION OF ANIMAL TRANSGENIC

1- Agriculture like improve Biomass

2- Disease Resistance like avian influenza.

3- Recombinant Vaccines for poultry

4- Livestock Pharming – Products like

myelin production
