Example of a GM Animal:

These two salmon are the same age,

but the GM salmon grew at about twice

the rate.

**It is more difficult to genetically modify animals than

plants.

What are the risks of GMOs?

What is Gene Therapy?

We rely on our genes functioning correctly, so when a gene is missing or not functioning, a ________ can result.

Gene therapy is a way of putting the _______ gene

back into our cells.

disease

correct

How is it done?

Vectorcarries the

new gene to the cells.

Will this individual produce offspring with the normal gene?

No, because the sex cells were not

altered.

Challenges of Gene Therapy:

1)The vector itself could cause the individual to become _____.

2) The gene has to be delivered tomany & the right kinds of ______.3)The gene needs to be inserted in the right part of the cell’s _______.4) The gene, once present, needs to be

__________.
