After this stage, ARN is subjected to the splicing which shortens it in the main
part to code one, only one protein because according to his splicing ARN can
code for other proteins.
And to finish, mature said ARN undergo the translation, made by means of the
genetic code and so to create the polypeptidique chain.
When the gene expresses himself in the way that the scientist wished
it, he so found the good GMO
And the Aquadvantage salmon?
In this case, the gene is directly modified in eggs of fish produced by the
company Aquabounty. Two genes are modified there with the aim of decreasing
their time of growth which passes from 3 years to 18 months.
Both modified genes arise from other fish. The first gene we modified, is the
gene coding for the growth hormone. Indeed, the scientist Aquabounty inserted
the gene which codes for this hormone at the salmon chinook. The second
modified gene is the one which codes for the said protein "anti-freeze agent" to
the pout, the Atlantic fish which so allows the GMO salmon to grow up all year
round while before it grew up only during certain periods of the year.
In conclusion, by modifying
two genes of the salmon, the
scientists allowed it to a stronger
growth. Indeed, by allying a
stronger growth hormone and an
anti-freeze protein, the salmons
saw their time of growth almost
divided by two.
