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.

Ovaj sveučilišni priručnik napisalo je petnaestak autora iz desetak visokoškolskih ustanova iz Zagreba i Rijeke, a sadržaj je podijeljen u petnaest, slikama bogato ilustriranih poglavlja u kojima su opisane i obrađene različite bakteriološke, virološke, mikološke, imunološke i molekularno-biološke metode koje se upotrebljavaju u općoj mikrobiologiji koja se studira na nizu različitih fakulteta i visokih škola.
Radi se o vrhunskoj literaturi za potrebe visokoškolske nastave iz veterinarske imunologije. Knjiga je svojim sadržajem namijenjena prvenstveno studentima, ali i veterinarima u praksi i nastavnicima.
(Iz recenzije)
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.
