DNA Structure
Highlighted Reports on the CRISPR Cas System!
Selected papers for CRISPR Cas! Segal and Meckler in 2013 state in ‘Genome Engineering at the Dawn of the Golden Age,’ that, “In summary, compared with ZFNs, TALENs can be designed for more targets, are more likely to be active… Read More ›
Is Targeted Insertion of Short DNA Fragments into Mammalian Cells Possible?
Recently the Targeted Insertion of Short DNA Fragments into Mammalian Cells was Shown to be Possible with the help of CRISPR Cas! The direct injection of Cas9 mRNA, sgRNAs, and DNA oligos or vectors into mammalian cells was reported as… Read More ›
What is a CRISPR Cas system?
The CRISPR-Cas systems found in bacteria and archaea are versatile small RNAs for adaptive defense and regulation Bacteria and archaea have evolved various defense and regulatory mechanisms allowing them to react to various stressful situations caused by the environment, such… Read More ›
What are Circular Oligonucleotides?
Circular oligonucleotides are covalently closed singular DNA or RNA strands that are resistant to degradation by many cellular DNA and RNA decay machineries. [Source: (left) Modelling DNA; Phil. Trans. R. Soc. A-2006-Harris-3319-34; (right) David Goodsell: The self-splicing RNA in PDB… Read More ›
Are viruses hiding within us?
Recent research results indicate that viral sequences are part of us. Endogenous viral elements (EVEs) or endogenous retroviral elements (ERVs) have been identified in eukaryotic genomes including the human genome. The findings revealed the enormous scale of the invasion of… Read More ›
RNA FISH can be used to visualize subcellular locations of RNA or RNA-RBP complexes including the location of noncoding RNAs !
RNA FISH allows the identification and localization of noncoding RNAs in cells ! Ribonucleic Acid Fluorescence In Situ Hybridization (RNA FISH) is a visualization technique that allows simultaneous detection, localization, and quantification of individual RNA molecules at the subcellular level….

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 ›
DNA Methylation
What is DNA Methylation? . DNA methylation is a biochemical reaction that adds a methyl group to DNA nucleotides. The methylation of DNA has been found to alter the expression of genes in cells during development. BSI can help you… 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 ›
