Binary trees are fundamental data structures in computer science, providing an efficient way to organize data hierarchically. When traversing these trees, we often uncover intriguing computational problems. Among these, identifying the lexicographically smallest palindromic path is a fascinating challenge. This article elucidates an effective C++ algorithm to solve this problem and provides a detailed example for better understanding. Problem Statement In a binary tree where each node represents a lowercase English letter, our objective is to discover the lexicographically smallest palindromic path. If several paths qualify, we can return any of them. If no palindromic path exists, we should return ... Read More
Keywords Genetic marker, DNA sequence, chromosome, variation, mutation, minisatellites, protein variation, genetic mapping. Introduction A genetic marker is a known location of a gene or DNA sequence on a chromosome which is used in the identification of individuals or species. It is described as a variation or mutation in a DNA sequence surrounding a single base-pair change or a long one, like minisatellites. Gene markers help in the identification of genetic characteristics like blood groups and protein variation. Examples of genetic markers are single polymorphism nucleotides (SNPs), restriction fragment length polymorphisms (RFLPs), variable number of tandem repeats (VNTRs), microsatellites, and ...

In this problem statement, our task is to find the average of the array excluding minimum and maximum values from the array with the help of Javascript functionalities. This task can be done by excluding the minimum and maximum values and calculating the average of the rest of the elements. Logic for the given problem To create the program for this problem we will use the Math function of Javascript to get the minimum and maximum values with the help of min and max keywords. After we are having the values of min and max now we will ... Read More
Introduction Distributed Computing Environment (DCE) refers to a software technology that delivers a framework for designing and executing dispersed applications in networked computing environments. During the 1980s and 1990s, the Distributed Computing Environment was developed by DCE by the Open Software Foundation (OSF) as a collection of standards and technologies for building distributed computing systems across various hardware, operating systems, and network environments. DCE has developed over the years, and its standards and technologies have been incorporated into diverse other distributed computing frameworks and technologies. Architecture of DCE The architecture of DCE (Distributed Computing Environment) depends on ... Read More
In this problem statement, our task is to find all the possible odd length subarrays with the help of Javascript functionalities. This task can be done with the help of some built in functions of Javascript or we can solve it by multiple for loops. Logic for the given problem The problem stated that we have to get all the possible odd length of the subarrays in Javascript programming language. The meaning of add length is that the length of the subarrays should be 1, 3, 5, 7, .....end so on. So our task is to filter the length ... Read More
Keywords DNA annotation, genome annotation, genetic material, genomic position, genomic databases, database records, eukaryotic genome, annotation tools, prokaryotic genomes. Introduction DNA annotation or genome annotation is the process of identifying the locations of genes and all the coding regions in a genome and determining what those genes do. An annotation is a note added by way of explanation or commentary. Once a genome is sequenced, it needs to be annotated to make sense of it. For DNA annotation, a previously unknown sequence representation of genetic material is enriched with information relating genomic position to intron-exon boundaries, regulatory sequences, repeats, gene ...

Keywords DNA sequences, small fragments, genetic sequencing, capillary electrophoresis, nucleotides, genome. Introduction Shotgun Sequencing and Next Generation Sequencing have the key difference i.e., Shotgun Sequencing is a sequencing method which randomly breaks up DNA sequences into many small fragments and reassembles the sequence by observing the overlapping regions. While Next Generation Sequencing (NGS) is an advanced method of genetic sequencing which depends on capillary electrophoresis. Sequencing is the process that determines the precise order of nucleotides in a gene, a cluster of genes, chromosome, and a complete genome. It is very important in genomic studies, forensic studies, virology, biological ... Read More
Introduction to DCF In fibre optic communication systems, dispersion compensating fibre (DCF) is an optical fibre used to lessen the phenomena that result in signal distortion and spreading over long distances. By using a fibre with a dispersion opposite to that of the transmission fibre, DCF is intended to account for chromatic dispersion, the most prevalent type of dispersion. It is applied to optical communication systems to boost bandwidth and range. DCF is a crucial component of high-speed communication networks, notably in long- and ultra-long-haul optical transmission systems. DCF Working Principle To take into account the dispersion that happens ... Read More
Keywords Genetic manipulation, gene expression, Cre recombinase, recognition site, P1 bacteriophage, genomes, recombination. Introduction Cre-Lox is a powerful tool for genetic manipulation in vivo because it allows for excellent spatial and temporal control of gene expression. This is invaluable when working with animal models, where unchecked gene expression or complete gene knockout may be detrimental or lethal. As the name suggests, the Cre-Lox system relies on two components to function: a Cre recombinase, and its recognition site, loxP. These components have been adapted from the P1 bacteriophage for use in genetic manipulation. LoxP sites are directional 34 bp sequences made ... Read More
Keywords DNA sequencing, next-generation sequencing, genetics, sequencing cost, study design, rare variant, nucleotide. Introduction Coverage is one of several measures of the depth or completeness of DNA sequencing and is more specifically expressed in genetics. Coverage describes the number of sequencings reads that are uniquely mapped to a reference and “cover” a known part of the genome. Ideally, the sequencing reads that uniquely aligned are uniformly distributed across the reference genome and hence provide uniform coverage. The number of sequencings that reads that map to a known region is also an important part of coverage. Coverage is not uniform and ... Read More
