Primer Approximation Multiplex PCR (PAMP) is a recently introduced experimental technique for detecting large-scale cancer genome lesions such as inversions and deletions from heterogeneous samples containing a mixture of cancer and normal cells. In this chapter we will first review previous solutions for the problem of selecting sets of PAMP primers that minimize detection failure probability and subsequently review Read More

Olfactory receptors, in addition to being involved in first step of the physiological processes that leads to olfaction, occupy an important place in mammalian genomes. ORs constitute super families in these genomes. Elucidating olfactory receptor function at a molecular level can be aided by a computationally derived structure and an understanding of its interactions with odor molecules. Experimental functional analyses of ol Read More

Molecular genetic markers represent one of the most powerful tools for the analysis of genomes and enable the association of heritable traits with underlying genomic variation. Molecular marker technology has developed rapidly over the last decade and two forms of sequence based marker, Simple Sequence Repeats (SSRs), also known as microsatellites, and Single Nucleotide Polymorphisms (SNPs) now predominate applicati Read More

Digital Signal Processing (DSP) applications in Bioinformatics have received great attention in recent years, where new effective methods for genomic sequence analysis, such as the detection of coding regions, have been developed. The use of DSP principles to analyze genomic sequences requires defining an adequate representation of the nucleotide bases by numerical values, converting the nucleotide sequen Read More

An original software package for determination of biological age has been offered. The package is simple for understanding and convenient in application. It is designed for the users who are not professionals in the fields of applied statistics or computer science. The problems and the algorithms realized in the package, the features and the possibilities of their application are described in brief. The package can be used Read More

Biological pathways information has accumulated along with Genomic sequence data. These metabolic pathways help us in understanding network robustness and complex reaction networks. They also provide a framework for improved understanding of microbial physiology and for antimicrobial drug discovery. This article is an attempt to understand the local and global properties of metabolic networks in P. aerugin Read More

Proteins are the molecules of life which are involved in cellular processes. The functional specificity of a protein is linked to its structure. A great section of bioinformatics deals with the prediction, analysis and visualization of protein 3D structures. High-throughput methods for the determination of protein structures provide the information needed to build structure-activity relationships. The accessibility of these str Read More
