Proteins in a membrane are

• integral if they protrude from only one surface of the bilayer.

• peripheral if they are on the inside surface held in place by the cytoskeleton.

• integral if they are embedded in the membrane and protrude from both surfaces of the bilayer.

• All of the choices are correct.

Which of the following characteristics of Taq polymerase make it useful in the PCR process?

• It is heat stable and can withstand the heating step of PCR.
