Question

I need some help in Biology!

Scenario 1:

Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.

Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)

What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 po

Answer 1

@leonardo0430, @tmak11, @YanaSidlinskiy, or @ganeshie8 can any of you help me?

Answer 2

Don't go crazy!!;) I think I'll be able to help youxD!1

Answer 3

yay!!
Thnx so much Yana!!

Answer 4

I have another scenario if u want to give it a look and see which one is easier...

Answer 5

Go ahead and post the other scenario.

Answer 6

Scenario 2:

Mike was adopted, and his biological family history is unknown. Although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. These tests can cost more than $2,500 and are not covered by many insurance companies.

Do you think that Mike should undergo the genetic tests? Explain your answer. (2 points)

What are potential pros and cons of having such tests done? (5 points)

Describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations. (3 points)

Answer 7

One of the problem that exists with tampering genes is that it is incredibly hard to accurately predict the outcomes of changing the genetic code of the animal you are working on over extended periods. Since there are complex interactions associated with each portion of the genome, and many have yet to be mapped or even discovered. Of course since you know what kind of outcomes you're expecting from the engineering process of the gene (such as fatter meat, better resistance to infections etc), but side effects like cancer, infectious disease (prions mentioned by lemontheif), elevated steroid/hormones can arise unexpectedly as a result. And if such side effects arise, they can ultimately harm the humans who consume them, this can potentially result in a pandemic if the disease has no known cure/treatment.

More indirectly, infectious resistant animals also provide an excellent environment in which superbugs can evolve. You may be able to prevent some infections caused by bacterial species initially by making them more resistant. But bacteria and viruses can also evolve and adapt to the changes made in their own environment, and if such is the case, you can potentially end up with a superbug that is resistant to antibiotics and host immune systems, this is the last thing anyone would want. And if such superbugs have adapted in these farm animals, it would be very bad that they end up in humans who consume them.


Because of this the risks really seems to outweigh the benefits here in my opinion, I think this method isn't really a good way to go about as of right now.
I was writing this like for 5 or 10 minutes nowxD!!

Answer 8

I'm confused, can u shorten that a little?

Answer 9

What are you confused on?

Answer 10

I jus cant quite change them into smaller sentences nor I understand what its saying... im a litttle confused in all :P

Answer 11

Just give me a sec. I think I can change it up a little. Not sure thoughxD.

Answer 12

Also, wat scenario is that?

Answer 13

The first one.

Answer 14

I'm still confused :p

Answer 15

:P Umm...Oh wait!!

I give up!! I hate myselfxD!!! Ughghgh!!!

Answer 18

Lol its ok :P
I have to go anyway, @leonardo0430 can u help?
I'll come back later at around 12-1

Answer 19

I'll create a new question later and I'll add u guys!
Thnx for trying to help Yana!
I still appreciate it ^_^
Ttyl! C ya guys!

Answer 20

You're welcome and ttyl/

Answer 21

to be honest i dont remember a thing about this sorry :/
