Question 1 2.5 / 2.5 pts Indicate whether each of the following descriptions better applies to COPI- (1), COPII- (2), or clathrin- (3) coated vesicles. Your answer would be a four-digit number composed of digits 1 to 3 only, e.g. 1322. ( ) They mediate transport from the ER to the cis Golgi network. ( ) Their coat protein forms a three-legged structure called a triskelion. ( ) They are pinched off from their donor compartment by a dynamin collar. ( ) They are involved in retrograde trans...

BIO 2120 Exam 3 - Questions and Answers What is the key to maintaining the functional organization of a cell? The selectivity of vesicular transport- vesicles must recognize and fuse only with the appropriate target membrane Transport vesicles from the ER are coated with ___. Cytosolic coat proteins- coats assemble as the vesicle buds off and are removed in the cytosol before it reaches its target. The vesicles fuse with the target membrane, empty their cargo, and their membrane proteins diffus...

CBSE Biochem Lesch-Nyhan Syndrome: what causes it and what are manifestations? - correct answersHGPRT deficiency in purine salvage pathway (this enzyme normally converts hypoxanthine to IMP and guanine to GMP). This deficiency leads to excessive Uric acid production and de novo purine synthesis. It is X linked recessive. Symptoms: hyperuricemia, gout, aggression / self mutilation, mental retardation, dystonia. Treatment for Lesch-Nyhan? - correct answersAllopurinol / febuxostat second ...
