4. AIDS
Can you help me? Someone? Ms.Sue why does it seem like you are ignoring me? Just asking. Because you have answered other peoples questions but not any of mine. Please help me I really need it. =(
This Girl -- I'm not ignoring you. However, I know very little about science and cannot help you.

I see. That is okay.
Thanks for the link.
1. Your answer for question 1 is correct. Gene therapy is a type of genetic engineering in which normal alleles are inserted into a virus and then used to replace faulty alleles in the patient's cells.
2. Your answer for question 2 is incorrect. The correct answer is recombinant DNA; bacterium. Recombinant DNA technology involves inserting DNA from one organism into the DNA of another organism, and in this case, human insulin can be produced by introducing the human insulin gene into the DNA of a bacterium.
3. Your answer for question 3 is incorrect. The correct answer is selective breeding. Selective breeding is a method used to improve the phenotype of plants by selecting individuals with desirable traits and allowing them to reproduce, thereby passing on those traits to subsequent generations.
4. Your answer for question 4 is incorrect. The correct answer is cystic fibrosis. Gene therapy holds promise for the treatment of cystic fibrosis, a genetic disorder that affects the lungs and digestive system. It involves introducing a normal copy of the defective gene into the patient's cells to improve their function.
