As of December 2013 90 solved structures were available in the PubMed structural database related to the CRISPR Cas System! -.- A few these models are shown below! A PubMed search for “CRISPR Cas” showed that close to 90 solved… Read More ›
RNA silencing
Are MicroRNAs the new players in metabolism and metabolic disorders?
Micro RNAs (miRNAs) have recently emerged as key regulators of metabolic processes! . More and more evidence is accumulating that suggest that the dysregulation of miRNAs may contribute to metabolic abnormalities such as the misregulation of cholesterol and lipid metabolism, insulin… Read More ›
Piwi-RNAs, the Defenders of the Genome
What are Piwi- or piRNAs ? Here is the answer: P-element induced wimpy testis (Piwi)-RNAs, or Piwi-interacting RNA, or piRNAs are small RNAs typically 23 to 35 nucleotides long . . During the recent 16 years a group of small… 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 ›

The RNA world is still expanding !
The ever expanding world of RNA RNA or ribonucleic acids differ from DNA or deoxyribonucleic acids in having the sugar ribose in place of deoxyribose as well as having one less oxygen atom at the ribose. Secondly, in RNA the… Read More ›
What do long noncoding RNAs and Pseudogenes do?
Pseudogene long noncoding RNA networks appear to regulate transcription and translation in human cells. What are pseudogenes? Pseudogenes are now thought to be nonfunctional relatives of genes and can be defined as fragments of nucleotide sequences that resemble a domain… Read More ›
A brief history of Bridged Nucleic Acids (BNAs)
By Klaus D. Linse 01/03/2013 A quest for better oligonucleotide mimics. The quest for oligonucleotide mimics with improved characteristics and stabilities useful for molecular diagnostics and therapeutics that also show minimal side effects has led to the design and synthesis… Read More ›
