Thermodynamics of DNA Hybridization


Knowledge of DNA thermodynamics is crucial for the design of PCR probes or any other oligonucleotide based hybridization probe! . Since DNA hybridization does not strictly follow the Watson-Crick pairing rules DNA hybridization experiments often require optimization. A DNA oligonucleotide… 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 ›
