Biology Homework - Genetic Engineering

Genetic Engineering

Question:

In the 1990s large crops of cotton plant were destroyed by the bollworm moth. The pesticides used to kill the moth were expensive and very poisonous, resulting in deaths to humans. Scientist investigated alternative ways to control the bollworm moth. They found out that a type of bacteria produces a poison which can kill the bollworm larvae (grubs). A GM cotton crop plant was developed which produced the same poison to kill bollworms. This proved very effective, and as a result farmers were able to stop using pesticides sprays. The GM cotton was genetically engineered to produce the same poison as the bacterium. Describe fully how this is done. (6 Marks)

Thanks so much VERY VERY VERY MUCH TTATT LIFE SAVER CHINGUUS TTATT

i haven't done biology for AGES XD heh heh my friends were doing something about genetics and some like diseases and all... disorders

There are three major steps for this process . First, you have to clone the gene from the bacteria and must locate and copy it this is called gene cloning.
Second, you have to choose which one produces the poison which can kill the bollworm larvae from the thousands of genes that were extracted .
Lastly, you have to transfer the gene into the cotton plant.The gene may be modified slightly to work in a more desirable way once inside the cotton plant. and the cotton now is genetically engineered to produce the same poison as the bacterium.

i think, they made a few change on the enzyme chain. they insert the bacteria's rna to the plant's dna.
hmm.. are you in highschool? i remember studying this topic in my second tear...

Yeah, sorry. I failed biology and just graduated without it. I'm a bit more basic in the genetics department. I really wish I could help.

wow. you're 14 yet your homework is....... damn. wow.
I'll try to help you with this homework. here, I think this link is good enough to answer your question, but of course you still have to develop it. http://mv.picse.net/pesticides/cotton/how-was-bt-cotton-produced/
hope this helps! fighting!

._____.' damn. lmaooo. WHERE'S THE MATH IN THIS?! XD CALL ME WHEN IT'S ALGEBRA, GEOMETRY, CHEMISTRY OR HISTORY CHINGU! XD

I can briefly describe it, can't give you a full answer but you can develop. So scientists are now able to isolate genes and we know genes control functions. If they can identify the gene that produces the poison, they can isolate it and take it out of the bacteria and graft it into the root cells I think of the plant as they are like the baby/stem cells of plants and then if it's successful, the plant should also have the function. That's the gist of it, sorry I can't be of more help.
