Four-strand DNA structure found in cells

Unusual nucleic-acid structure may have role in regulating some genes

There is no more iconic image in biology than that of DNA’s double-stranded helix, which coils and supercoils on itself to form dense chromosomes.

But a quite different, square-shaped type of DNA structure can easily be created in the laboratory by the folding of synthetic DNA strands rich in guanine, one of the building blocks of DNA. Scientists have long believed that these so-called ‘G-quadruplex structures’ may occasionally form in the DNA of living cells. A G-quadruplex comprises four guanines from different places along a G-rich strand held together by a special type of hydrogen bonding to form a compact square structure that interrupts the DNA helix.

In a paper published online today in Nature Chemistry, researchers led by Shankar Balasubramanian at the University of Cambridge, UK, provide strong evidence that G-quadruplexes do occur in cells — and that these unusual structures may have important biological functions.

Probiotics are mostly useless and can actually hurt you
Probiotics are living micro-organisms that are taken by millions of people to boost their microbiome or to restore their gut ecosystem after a dose of antibiotics. Yet questions remain about whether they actually work.

Moćni mikrobi – prikaz knjige Mighty Microbes – The Amazing World of Microorganisms

Skupina znanstvenika i popularizatora znanosti iz Nizozemske se s ovom idejom pozabavila kroz fundaciju Microcanoni, nizozemsku inačicu projekta naziva „Što doista trebate znati o mikrobiologiji“ još 2011. Ta verzija prezentirana je i u amsterdamskom muzeju Artis Micropia, a djelo na engleskome čiji vam prikaz donosim je korak dalje koji je ova skupina ljudi poduzela u ulozi urednika knjige s naslovom Mighty Microbes i podnsalovom The Amazing World of Microorganisms. Osmislili su građu podijeljenu u devet tematskih cjelina, a unutar svake je pet do deset poglavlja (tema) za koje su kao autore ili suautore odabrali znanstvenike koji su sudjelovali u ključnim otkrićima ili su istaknuti stručnjaci u tom području.
