11. What is genetic engineering? What differentiates modern genetic engineering from conventional plant and animal breeding? Give an example of a tool/method used for conventional breeding, for genetic engineering. Compare the source of genes, amount of genetic change, and extent of characterization of the introduced genetic material, in the different methods.

Q

7. The things that are True about animal breeding are…(check all that are correct)

___a. animal breeders need to select the parents carefully

___b. breeding can only be done between 2 animals of the same species.

___c. animal breeders have a goal of improving a trait or traits in their breed or species of animal

___d. they all have the same traits they want to improve, no matter what the animal species or breed.

___e. animal breeders are only interested in traits for which selection is obvious and the genetic control or inheritance is easy to predict

___f. animal breeding is only done on domestic animals not wild animals

___g. animal breeding would be much easier if there was no variation within a species in the genes that control their traits.

___h. although slightly more difficult, breeding between 2 different species (ex. cat and dogs) can be done just as breeding within the same species.

Q8. Describe two differences and two similarities between plant breeding and animal breeding.

By using the techniques of genetic engineering, scientists are able to modify genetic materials so that a particular gene of interest from an animal cell can be incorporated into a bacterial cell for gene expression. Describe a procedure by which this can be done with a cloning vector. Explain the purpose of each step of your procedure. Describe how you could determine whether the bacteria take up the vector and whether the gene was successfully incorporated. Describe an example of how this gene transfer and expression is used in biomedical or commercial applications.
