The budding of clathrin-coated vesicles from eukaryotic plasma membrane fragments can be observed when adaptations, clathrin, and dynamin-GTP are added to the membrane preparation. What would you observe if you omitted (A) adaptations, (B) clathrin, or (C) dynamin

Explanation:

Adaptins:

Adaptor proteins, which attach the clathrin to the membrane, are required for clathrin-coated vesicles to form. Clathrin cages form in solution at strong clathrin concentrations and under the right ionic environments and parameters, but they are empty hollow shells without membranes or other proteins. The data for clathrin baskets are included in the clathrin molecules themselves, as shown by the self-assembly of clathrin into baskets. Clathrin coat cannot form or build up without adjusting to the membrane it is attached to.

Clathrin:

Adaptins bind and act synergistically to specific receptors without clathrin, but no vesicles or clathrin are formed. There exists coated pits formations, but no clathrin coat.

Dynamin:

Clathrin-coated pits can develop and progress toward vesicle formation in the exclusion of dynamin, but the final step, known as membrane fusion, is inhibited. Consequently, in the exclusion of dynamin, strongly invaginated covered pits will be noticed. As a result, vesicles are unable to pinch the membrane.

Suppose plasma membrane fragments were prokaryotic cells, there would be no endocytosis and hence no adaptin or coatings. Endocytosis is not performed by prokaryotic cells. There are no receptors with adequate cytosolic tails in a prokaryotic cell that might facilitate the binding to adaptor proteins. As a result. no clathrin-coated vesicles will develop.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

sorry, is there a picture? i do not see any arrows.
