Single nucleotide RNA choreography
New structural analysis methods, and a tree formalism re-define and expand the RNA motif concept, unifying what previously appeared to be disparate groups of structures. We find RNA tetraloops at high frequencies, in new contexts, with unexpected lengths, and in novel topologies. The results, with broad implications for RNA structure in general, show that even at this most elementary level of o...
متن کاملSingle Nucleotide Polymorphism Analysis of Protamine Genes in Infertile Men
Background Single nucleotide polymorphism (SNPs) are considered as one of the underlying causes of male infertility. Proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. Over 20 SNPs have been reported for the protamine 1 and 2. MaterialsAndMethods The aim of this study was to evaluate the frequency of two previously repo...
متن کاملSingle Nucleotide Polymorphisms and Association Studies: A Few Critical Points
Uncovering DNA sequence variations that correlate with phenotypic changes, e.g., diseases, is the aim of sequence variation studies. Common types sequence variations are Single nucleotide polymorphism (SNP, pronounced snip).SNPs are the third-generation molecular marker. SNP represents a DNA sequence variant of a single base pair with the minor allele occurring in more than 1% of a given popula...
متن کاملSingle-molecule choreography between telomere proteins and G quadruplexes.
Telomeric DNA binds proteins to protect chromosome ends, but it also adopts G quadruplex (GQ) structures. Two new studies by Hwang and colleagues (in this issue of Structure) and Ray and colleagues (published elsewhere) use single molecule imaging to reveal how GQs affect the binding of different telomere associated proteins. The data suggest that GQs play important roles in regulating accessib...
متن کاملSingle-Nucleotide Polymorphism Masking
Microarrays are widely used to evaluate gene expression at the genome scale. However, all too often the importance of data analysis at the level of the individual probe is overlooked. This is a particular problem when trying to detect differences in gene expression levels among genetically unique animals, across inbred animal strains, or among genetically modified animals. Of particular concern...
