I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#’Bystander’ cytosines meet their match in gene-editing technique” When consecutive cytosines are positioned in the editing window, the new A3G base editor developed at Rice University precisely modifies the single targeted C while minimizing unwanted C editing. Credit: Gao Lab/Rice University Biomolecular engineers at Rice University have found a C-worthy technique that dramatically enhances the…
“#Scientists uncover key process in the manufacture of ribosomes and proteins” Negin Khosraviani, Karim Mekhail and Karan (Josh) Abraham. Credit: University of Toronto Researchers at the University of Toronto have shown that an enzyme called RNA polymerase (Pol) II drives generation of the building blocks of ribosomes, the molecular machines that manufacture all proteins in…
“#Molecular ‘tails’ are secret ingredient for gene activation” Credit: Pixabay/CC0 Public Domain It might seem as though humans have little in common with the lowly yeast cell. Humans have hair, skin, muscles, and bones, among other attributes. Yeast have, well, none of those things. But besides their obvious differences, yeast and humans, and much of…
“#Scientists achieve first complete assembly of human X chromosome” Credit: CC0 Public Domain Although the current human reference genome is the most accurate and complete vertebrate genome ever produced, there are still gaps in the DNA sequence, even after two decades of improvements. Now, for the first time, scientists have determined the complete sequence of…
“#Finding the missing step of an important molecular process” This figure shows how bacterial and plant lysine catabolic pathways converge, while the highlighted box shows the enzymatic mechanism of the enzyme the researchers discovered and characterized. Credit: US Department of Energy Lysine is an important amino acid that must be supplied in our diets, as…
“#Synthesizing an alternative fuel for muscle could lead to medical advances” Myosin with azoTP and ATP in its active site. Credit: UMass Amherst/Debold lab A chemist and kinesiologist got on a bus, but this isn’t the set-up to a joke. Instead, kinesiologist and lead author Ned Debold and chemist Dhandapani Venkataraman, “DV,” began talking on…
“#Turning off ‘junk DNA’ may free stem cells to become neurons” NIH scientists showed how ancient retroviral genes, or “junk DNA”, may play a role in helping stem cells decide to become neurons. Credit: Nath lab, NIH/NINDS. For every cell in the body there comes a time when it must decide what it wants to…
“#Power of DNA to store information gets an upgrade” Credit: CC0 Public Domain A team of interdisciplinary researchers has discovered a new technique to store in DNA information—in this case “The Wizard of Oz,” translated into Esperanto—with unprecedented accuracy and efficiency. The technique harnesses the information-storage capacity of intertwined strands of DNA to encode and…
“#Human sperm stem cells grown in lab, an early step toward infertility treatment” By applying an inhibitor of the molecule AKT, UC San Diego researchers are able to favor the culture of human spermatogonial stem cells in the lab, a first step toward lab-produced sperm as a treatment for male infertility. Credit: Vishaala Wilkinson Infertility…
“#The colorful history of plastids” Schematic evolutionary tree of eukaryotes with an emphasis on photosynthetic lineages. Members of the Archaeplastida have primary plastids stemming directly from cyanobacteria. The primary plastids of red and green algae have spread from the Archaeplastida to other branches of the tree, including Rhizaria, Discoba, and Stramenopila. The colored taxon names…
