Evaluate the Rab protein cycle and explain how Rab proteins reversibly interact with the membranes

Why protein folding usually starts before translation is complete and misfolding of proteins often results in protein aggregation?

Briefly describe the major stages of translation. At what stage regulation of translation process is the most efficient? Why? 

What are similarities and differences between retrograde and anterograde transport in neurons?

Why alternative splicing is widespread among multicellular organisms?

What is a biological role of actin in the cells of higher plants?

Illustrate your answer with one-two examples.
