Which of the following would definitely be classified as a GE? A bacterium that has been treated with a compound that affects the expression of many of its genes All of these are GE A human treated with insulin produced by E. coli bacteria A turkey treated with hormones A rat with rabbit hemoglobin genes inserted into its genome

A rat with rabbit hemoglobin genes inserted into its genome

What is a major difference between genetic engineering (GE) and genetic modification (GM)? GM could have happened in nature, while GE could never happen in nature. Actually, GM and GE are different names for the same thing and there are no major differences. GE could have happened in nature, while GM could never happen in nature. GM happens in plants while GE only happens in animals.

GM could have happened in nature, while GE could never happen in nature.

During the cloning process, why couldn't you use a gamete to obtain the DNA that is added to empty egg cell? Gametes do not contain DNA. Gametes are harder to get DNA from. Gametes contain twice the DNA needed. Gametes contain only half the DNA needed.

Gametes contain only half the DNA needed.

Based on the case study we did in class, what would demonstrate that a cloning attempt was successful? The proteins in the offspring are the same as the donor. The offspring looks like the donor. The offspring DNA is virtually identical to the donor. The results of the cloning attempt are published.

The offspring DNA is virtually identical to the donor.

What is the major difference between reproductive and therapeutic cloning? Whether an embryo is created or not. Whether a clone of an organ or a clone of a single cell is created. Whether an egg is used that has the nucleus removed or an extra nucleus added. Whether the embryo develops in a surrogate or stem cells are collected.

Whether the embryo develops in a surrogate or stem cells are collected.
