THE GENE DEBATE



INTRODUCTION:


We have prepared a debate with different topics,

the cloning vegetable i the genetically modified food.

We will speak about these topics exposing the

advantages and the disadvantages.



GM FOOD:
What are GMO’s?


Genetic modification, also known as "genetic engineering” or “recombinant-DNA technology” was first applied in the 1970’s.

Genetically modified organisms (GMOs) can be defined as organisms in which the genetic material (DNA) has been altered.




DISADVANTAGES:

- Changes in the genetic endowment of wild plants whose effects on the ecosystem are still unknown.
- Cloning tend to uniformity
- The sale of genetically modified seeds is a monopoly of big business.

- The chemicals of the GM food might not be good for humans.

BENEFITS:

- Playing sterile plants, more pleasant to consume with size and texture more palatable.
- The genetically plants have more quality.

- Improve nutrition of certain populations that present deficiencies in nutrition.
CLONING ANIMALS:

DISADVANTAGES:

- Cost of the art high

- The cloning of animals also tend to uniformity

BENEFITS:

- Produce drugs or substances with useful for the investigation or livestock, from cells or tissues cloned.

- Secure copies of a copy that has shown good yields to prevent your good combination of genes will "dilute" the cross with another sexually.

- Salvation of some wildlife species threatened with extinction and difficult to breed in captivity.
