Question
A particular mature miRNA (microRNA) in mice has sequence 5'-UUCCCUGAGACCUCAAGUGUGA-3'.
a. If you wanted to predict which mouse mRNAs are regulated by this miRNA, what would you look
for? Choose one or more.
i. mRNA sequence the same as the miRNA sequence
ii. mRNA sequence complementary to the miRNA sequence
iii. mRNA sequence including a RISC binding site
iv.
mRNA sequence including 5'-CUCAGGGAA-3'
v. mRNA sequence including 5'-UUCCCUGAG-3'
b. Your sequence analysis predicts that 200 mRNAs may be targets of this miRNA. You engineer
mouse cells that produce an excess of this miRNA. For the real targets, we predict that
in these cells over-expressing the miRNA, compared to the unmodified cells.
Choose one or more, and explain.
i. The target gene is deleted in cells with an excess of the miRNA
ii.
The target is translated less in cells with an excess of the miRNA
iii. The target is translated more in cells with an excess of the miRNA
iv. There is more of the target mRNA in cells with an excess of the miRNA
v.
There is less of the protein product of the target mRNA in cells with an excess of
the miRNA
C.
vi.
There is more of the protein product of the target mRNA in cells with an excess
of the miRNA
Would you expect to find one or many mRNAs that are genuinely regulated by the miRNA?
One
Many
