miRNA complexes can cause ribosomes to fall off mRNA
prematurely.



The removal of the polyA tail by miRNA complexes causes the
mRNA to be digested by RiSC.



The RiSC complex, when directed my miRNAs, can cause mRNA to
become circular in structure which inhibits translation.



miRNA directed RiSC complexes can bind to ribosomal subunits
preventing the assembly of a functional ribosome (with large and
small subunit).




Question 2 pts



Which of the following statements are true concerning the
production of micro RNAs?



DGCR8 functions to position Dicer in the correct location to
produce pri-miRNAs.



DGCR8 binds at the base of the double-stranded stem loop to
position the first RNA cut site 11 bases up the stem (one helical
turn of RNA).



mir genes that are located in the exon region of another gene are
called mirtrons.



micro RNAs are endogenouse genes that produce RNAi without
the need for a viral infection.
