Best Answer

Although miRNA and siRNA both have gene regulation functions, there are subtle differences. MiRNA may be slightly shorter than siRNA (which has 20 to 25 nucleotides). MiRNA is single-stranded, while siRNA is formed from two complementary strands. The two kinds of RNA are encoded slightly differently in the genome. And the mechanism by which they regulate genes is slightly different.

MiRNA attaches to a piece of messenger RNA (mRNA) -- which is the master template for building a protein -- in a non-coding part at one end of the molecule. This acts as a signal to prevent translation of the mRNA into a protein. SiRNA, on the other hand, attaches to a coding region of mRNA, and so it physically blocks translation.

All RNAs (mRNA, rRNA, tRNA, siRNA, hnRNA) must be transcribed from DNA.
