Consider the following statements

$I$. Transgenic animals are more sensitive to the toxic substance than non-transgenic animals

$II$. Useful biological products can be produced by introducing into transgenic animals the portion of $DNA$ which codes for a particular product

$III$. Brazzein is a protein produced by a west African plant, Pentadiplandra brazzeana which is approximately $2000$ time as sweet as sugar

Which of the statements are given above are correct?

$I$, $II$ and $III$

$I$ and $II$

$I$ and $III$

None of these

Solution

Transgenic animals are made to carry genes which makes them more sensitive to the toxic substance then non-transgenic animals

$(i)$ Useful biological products can be produced by introducing into transgenic animals the portion of $DNA$ (or genes) which codes for a particular product, e. $g .$, human protein $i-1$-antitrypsin) is used to treat emphysema

$(ii)$ Brazzein is protein produced by a west African plant, Pentadiplandra brazzeana, which is approximately $2000$ times as sweet as sugar. It is used as a low calorie sweetener Local people have been using the super sweet berries of this plant for centuries. But the protein brazzein was patented in $USA$
