Abstract:
We describe a modified T-vector, pGFPm-T, for direct cloning of RT-PCR products to generate bidirectional restriction fragments for assembly of hairpin-containing RNAi vectors in the popular pFGC and pGSA binary vector backbone. Green fluorescence protein (GFP) is used as a visual reporter for direct selection of recombinants under UV illumination. The simplified cloning process enables a seamless workflow from candidate gene selection and RT-PCR verification to inverted repeat cloning, using a single pair of gene-specific primers.

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...

RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

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...
