Answer:
1. Designing of the target vector.
2. Insertion of the target vector into the embryonic stem cell
3. Selection of the cells
4. Injecting selected cells into the new cells
5. Breeding of mouse with a normal mouse
Explanation:
The target vectors are made by inserting markers into them. The target vector is inserted into ES cells. The vector generally recombined with the target gene and knock-out that gene. Sometimes, recombination of vectors occurs at incorrect place.
The cells survive in the presence of markers only if the target gene is incorporated with target vector. The cells with the target vector are injected into a normal developing embryo of mouse.
The developed mouse will consist of heterozygous knockout cells and its own cells. The normal mouse is bred with this chimeric mouse. The offspring of these mouse are able to transfer knock-out gene to next generation.
If your cell did not produce proteins enzymes would not be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins such as microtubules which would cause many other problems within the cell.

I think your answer should be B. an organism. Hope this helps. =^-^=
Answer:
an enzyme is specific which means that only one type of substrate can be broken down by it
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
