Morphological and molecular identification of filamentous fungi isolated from cosmetic powders
Brazilian Archives of Biology and Technology, 2012 Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp.

The unknotted strands of life: knots are very rare in RNA structures [PDF]
arXiv, 2014 The ongoing effort to detect and characterize physical entanglement in biopolymers has so far established that knots are present in many globular proteins and also abound in viral DNA packaged inside bacteriophages. RNA molecules, on the other hand, have not yet been systematically screened for the occurrence of physical knots.

Isolation and organization of calf ribosomal DNA
Nucleic Acids Research, 1979 Ribosomal DNA (rDNA) from calf was isolated by three density gradient centrifugations. The first centrifugation in Cs2S04/BAMD was used to obtain partially resolved dG+dC-rich fractions from total DNA. The second and third centrifugations, in Cs2S04/Ag+, led to the isolation of an rDNA fraction characterized by a symmetrical band in CsCl, p = 1.724 g ...

Catalogue of fungi in China 2. Ramaria from northern China
MycologyThe species of Ramaria are coralloid-fungi with intricately branched and vividly coloured basidiomata. There are many studies on the genus Ramaria in China, but molecular phylogenetic analysis is rarely employed.

Molecular interactions between the constituents of small ribosomal subunit [PDF]
arXiv, 2012 Availability of high-resolution crystal structures of ribosomal subunits of different species opens a route to investigate about molecular interactions between its constituents and stabilization strategy. Structural analysis of the small ribosomal subunit shows that primary binder proteins are mainly employed in stabilizing the folded ribosomal RNA by ...

Characterization of ribosomal DNA (rDNA) in Drosophila arizonae
Genetics and Molecular Biology, 2000 Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between ...
