Now, we will show you a new book enPDFd protamines isolation characterization structure and function that can be a new way to...
متن کاملAllelic Expression of Drosophila Protamines during Spermatogenesis
In typical somatic cells, DNA is tightly organized by histones that are necessary for its proper packaging into the nucleus. In sexually-reproducing animals, the haploid product of male meiosis must be further condensed to fit within sperm heads, thus requiring an even greater degree of packaging. This is accomplished in most organisms by replacing histones with protamines, which allows DNA to ...
متن کاملProtamines: structural complexity, evolution and chromatin patterning.
Despite their relatively arginine-rich composition, protamines exhibit a high degree of structural variation. Indeed, the primary structure of these histone H1-related sperm nuclear basic proteins (SNBPs) is not random and is the depository of important phylogenetic information. This appears to be the result of their fast rate of evolution driven by positive selection. The way by which the prot...
متن کاملHighly Sensitive Amperometric Sensor Based on Gold Nanoparticles Polyaniline Electrochemically Reduced Graphene Oxide Nanocomposite for Detection of Nitric Oxide
A sensitive electrochemical sensor was fabricated for selective detection of nitric oxide (NO) based on electrochemically reduced graphene (ErGO)-polyaniline (PANI)-gold nanoparticles (AuNPs) nanocomposite. It was coated on a gold (Au) electrode through stepwise electrodeposition to form AuNPs-PANI-ErGO/Au electrode. The AuNPs-PANI-rGO nanocomposite was characterized by Field Emission Scanning ...
