Preparation of short RNA by in vitro transcription
1Department of Biochemistry and Biophysics, Texas A&M University, College Station, TX, USA.
Abstract:
Short RNA oligomers are required in many biochemical and biophysical studies. In vitro transcription using T7 RNA polymerase can produce a large amount of specific RNA sufficient for structural studies in a more economical way than chemical synthesis. Here, we provided protocols optimized for the synthesis of very short RNA of 10-20 nucleotides in length by in vitro transcription. These RNA oligomers can be purified conveniently by gel filtration chromatography. We also described how to study RNA and protein binding by gel filtration chromatography.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
