In a hypothetical environment, fishes called pike-cichlids are visual predators of algae-eating fish (i.e., they locate their prey by sight). If a population of algae-eaters experiences predation pressure from pike-cichlids, which of the following should least likely be observed in the algae-eater population over the course of many generations?

Not surprisingly, in several instances, the two binding sites for the regulatory ribosomal protein are related to each another. In the case of the S8 ribosomal protein, the two binding sites share substantial similarities. The sequence of the binding site in the mRNA reveals a clear mechanism by which S8 inhibits translation. Which of the following are INCORRECT regarding this mechanism?

A. Free rRNA content in cytoplasm activates ribosomal protein biogenesis

B. RNA-binding proteins regulate their expression by binding to their own mRNAs, including some aminoacyl-tRNA synthetases

C. In case of “NO FREE rRNA” ribosomal protein transcript is efficiently translated by autoregulation process

D. In case of “NO FREE rRNA” ribosomal protein transcript undergoes to autorepression
