Abstract:
The multiple levels of post-transcriptional processing and million-fold differences in expression levels make fully decoding the transcriptome in any given species extremely challenging. This review addresses the influence of sequenced length on transcriptome decoding under current DNA sequencing capabilities. Comparison of full-length cDNA, EST, 14-base SAGE, 21-LongSAGE, 26-SuperSAGE, and other variations shows that the sequenced length has been a key factor in determining the sensitivity and specificity for mRNA detection.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
