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.

Veterinarska klinička imunologija

Iako je riječ o sveučilišnom udžbeniku, knjiga je po svom sadržaju i opsegu namijenjena i kolegama veterinarima koji rade u praksi, ponajprije onima koji se u svagdašnjem radu bave tzv. malom praksom.
