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.
miRNA
In normal transcription DNA is converted to RNA .reverse transcription is nothing but RNA will be converted to DNA
The process that involves the transcribing of genetic information from DNA to RNA is called Transcription.

Transcription
Do your own lab report. Jk. Transcription is the process in which DNA is converted into a complementary RNA. Before transcription, the splicing of introns has already occurred. Transcription takes place the nucleus. RNA polymerase begins the elongation of the RNA while the DNA template is unwound and rewound. Transcription responds to the termination signal and disassembles, terminating the process. The RNA is then processed with 5' G cap and poly A tail, and exits the nucleus, heading into the cytoplasm.
The nucleotides that are involved in transcription are known as uracil (U). This is what will be used in the RNA transcription to the ribosomes.
RNA transcription is when RNA coverts into DNA, which takes place in the ribosomes.
It is called reverse-transcription but the RNA is viral RNA and it infects the cell when it reverses to DNA.
Transcription.During transcription the base sequence (genetic code) of part (a gene) of one strand of DNA is copied onto a strand of RNA as the RNA is synthesized.
