4) Cell C suddenly lost all its dynamin proteins. Which of the following will most likely happen right
away as a result of this loss?
A) Transcription factor X will no longer be able to go to the nucleus
B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above

B) A vesicle bud will no longer be pinched off from a membrane

Explanation:

Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.

The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
