Bridged Nucleic Acid based FISH
Bridged Nucleic Acid (BNA) based FISH probes are smart tools available from Biosynthesis Inc. Recent advancements in the design and development of molecular probes and image analysis has made fluorescence in situ hybridization (FISH) a powerful tool. Although being a… Read More ›
What are Long or large non-coding RNAs (lncRNAs)?
Long or large non-coding RNAs (lncRNAs) are non-protein coding sequence transcripts ! . Long non-coding RNAs are non-protein coding sequence transcripts that contain more than 200 nucleotides. The size of these RNA molecules distinguishes them from small regulatory RNAs such… Read More ›
What are Micro peptides?
Micro peptides are short, unprocessed peptides with biological functions! . Do noncoding RNAs (ncRNAs) code for micro peptides? . Yes, apparently this appears to be the case! . In protein synthesis RNA acts as a template for cellular proteins and… Read More ›
What are MicroRNAs and what do they do?
MicroRNAs are small non-coding single-stranded RNA molecules MicroRNAs (miRNAs) are small non-coding single-stranded RNA molecules consisting of approximately 21 to 22 nucleotides that regulate posttranscriptional gene expression in metazoans and plants. miRNAs are usually generated from noncoding regions of gene… Read More ›
What are MicroRNA sponges?
MicroRNA sponges are decoy targets for miRNA seed families ! Ebert, Neilson & Sharp in 2007 report how to make decoy targets for several microRNA seed families, and named them ‘microRNA sponges’. Furthermore the researchers tested their ability to derepress… Read More ›
