Q89 - Functional Consequences of mRNA Circularization
mRNAs in the cytoplasm of eukaryote cells frequently form closed loops by circularization. Indicate in the answer sheet if each of the following statements concerning closed loops is true or false.
Using the information and data, determine which of the statements are true or which are false.
A. Circularization is due to a phosphodiester bond between the 5'end and the 3'end of mRNA.
B. Circularization increases stability of mRNAs.
C. Circularization enhances translocation speed of the ribosomes.
D. Controlling circularization is a mechanism of post-transcriptional regulation.
