Difficulties in detecting hybridization.
genome? To what extent do the particular assumptions made in the analysis (e.g., independence of sites, evolutionary model, same substitution rate across sites) affect the number and type of local maxima? Such questions provide a rich source for investigation into the efciencies of phylogenetic reconstruction methods.
متن کاملDetecting hybridization using ancient DNA.
It is well established that related species hybridize and that this can have varied but significant effects on speciation and environmental adaptation. It should therefore come as no surprise that hybridization is not limited to species that are alive today. In the last several decades, advances in technologies for recovering and sequencing DNA from fossil remains have enabled the assembly of h...
متن کامل8.5 Detecting Nucleic Acid Hybridization
The double-helical structure of nucleic acids, in which one strand binds specifically to its exact complement, could not have been designed to be more useful for the study of biology. The ease of designing assays based on this feature is responsible for the incredibly fast pace that has characterized molecular biology research since its inception. With the incorporation of fluorescence technolo...

Introduction: "Joubert syndrome" was first introduced in1969. This syndrome is a rare genetic disease with autosomal dominantpattern. Hypotonia, ataxia and motor delay of the disease known as clinical manifestations. In the few reports of this syndrome, mostly functional and structural components studied and radiographic images such as speech and language developmental delay symptoms has been l...
متن کاملDifficulties detecting miRNA-203 in human whole saliva by the use of PCR
OBJECTIVES Oral Lichen Planus (OLP) is a chronic disease of the oral mucosa, and according to the WHO also a pre malignant condition. Micro-RNAs are short non coding RNAs capable of regulating mRNA expression. MiRNA:scan be detected in tissue, blood and human whole saliva, HWS, and recently we have shown miR-203 to be up-regulated in tissue from OLP lesions. STUDY DESIGN In order to see wheth...
