This is an mRNA strand of mouse meta-globin:
5'-ccccagauacggaauucgaau-3'
A) Which small RNA (below) is most likely to regulate expression of meta-globin?
- 5'-auucgaauuuucuaucugggg-3'
- 5'-ggggucuaucuuuuaagcuua-3'
- 5'-ccccagauacggaauucgaau-3'
- 5'-uaagcuuaaggcauagacccc-3'
B) This RNA most likely?
- acts as an siRNA
- inhibit meta-globin translation
- increase meta-globin translation
- help transport meta-globin mRNA back into the nucleus
My attempt:
I think A is 2 because the strand is complementary and will bind nicely to the mRNA strand. For B, I'm between 2 and 3, but cant decide.
