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 ›

Tales of Genes and Proteins


Implications of the Human Genome Project The human genome project revealed that the human genome contains approximately 26,000 to 38,000 genes that code for proteins. This is significantly fewer than had been previously anticipated. It was found that protein-coding sequences… Read More ›

Happy DNA Week!


This week is the international DNA week! . This year we celebrate the 60th anniversary of the discovery of the DNA double helix by Watson and Crick which was achieved with the help of X-ray diffraction data produced by Rosalind… Read More ›
