Which is a genetic disorder that gene therapy may correct? (1 point)

type I diabetes

tetnus

AIDS

cystic fibrosis

My answers are:

2. recombinant DNA; bacterium
3. mitosis
4. AIDS
Was I correct?

1 and 2, yes

3 and 4, no

Improving phenotype has to due with reproduction and offspring. Not regular mitotic division. Selective breeding is method used to get desired traits by controlling reproduction.

AIDS is Acquired Immunodeficiency Syndrome which is passed from person to person generally via blood. Thus, it is not a disease that gene therapy could correct. The question asks for a genetic disorder which rules out tetanus (caused by a bacteria) and AIDS (caused by a virus). Type I diabetes is a bit deceptive...it is strongly genetic, but cystic fibrosis is definitely the answer. So Cystic fibrosis.

Good luck.

So is it cystic fibrosis? for number 4?

I am a senior in college, biochemistry is my major quite a bit further than 7th, but if this is the stuff you get taught in 7th grade then you go to a pretty good school.

Cystic fibrosis is what I would pick for number 4.

Smart isn't smart he's just rude. This girl its a TEST not a work with people to find the answer exercise. This is cheating, its a good thing you're not leaving your name or connections would find you and you'd be in trouble. I go to ORCA :3

All of the people here are cheating, you wouldn't find this if you didn't look.
