Travail sur les OGM

GMO2-

Introduction:

This introduction presents the subject of the text, it differentiates natural selection and

genetic engineering and it defines this term.

What happens when people engineer a gene? :

This paragraph deals with the beginning of genetic engineering and it contains a short

answer about the consequences of genetic engineering. People need to work to see if it

is worth modifying a gene.

Examples of genetic engineering and consequences:

Here, we can read examples of GMOs.

The first example shows the use for human health, here diabetes. On one hand, people

the environment, even if the yield is way better.

The third example is genetically modified rice that contains a lot of vitamin A, which is

very nice to reduce child blindness in poor countries. But people seem no to be happy

with this rice.

The fourth example shows genetically modified cows that produce milk without

beta-lactoglobulin, allowing lactose intolerant people to drink milk. it also allows

producing cheese easily. In 14 years, 0 disadvantage was found.

Conclusion:

GMOs are a very controversial subject, we need to see the pros and cons before

creating a new type of GMO. We need to ask ourselves this question: is it worth creating

it or not?

What is a gene and how is it used?:

this paragraph deals with how DNA works and the use of genetic engineering in lots of

domainsGene changes:

this paragraph shows the impact of a random mutation.

1- no impact

2- can have a dysfunctional cell or a die of a cell, but no overall harm.

3- if reproductive cell :

-no changes

-have a dysfunctional cell or a die of a cell

-change that causes more risk to be killed, so the individual can’t

reproduce and the change isn’t transmitted to the next generation.

-change that causes less risk to be killed, so the individual can

reproduce and
