Question 5

A researcher identified an uncharacterized mouse gene and the protein it encoded. The researcher prepared antibodies to the purified protein. To determine the specificity of the antibody the researcher incubated tissue sections from a knock-out mouse with the new antibody.

Question 8

With respect to knock-out technology, it has been said "If a protein's function is important, its knock-out will result in lethality. On the other hand, if it's very important its function will be duplicated by another protein, and there will be no obvious phenotype for the knock-out." Please explain this statement in your own words.
