RNA sequencing (RNA-seq) experiments now span hundreds to thousands of samples. A source of frustration for investigators analyzing a given dataset is the inability to rapidly and reproducibly align its samples jointly. Current spliced alignment software is designed to analyze each sample separately. Consequently, no information is gained from analyzing multiple samples together, and it

Researchers from the Istituto per le Applicazoni del Calcolo, CNR, Italy, have developed RNASeqGUI R package, a graphical user interface (GUI) for the identification of differentially expressed genes across multiple biological conditions. This R package includes some well known RNA-Seq tools, available at www.bioconductor.org. RNASeqGUI package is not just a collection of some known methods

from RPubs by Alex Chitsazan Overview This is a script that will do differential gene expression (DGE) analysis for RNA-seq experiments using the bioconductor package edgeR. Project Details To give background on this project, this is a RNA-seq project that is being done in planarian, Schmidtea mediterranea, a flatworm that has remarkable regeneration properties. This
The tiny torques of DNA have been directly measured in the lab of physicist Michelle Wang using an instrument called an angular optical trap.
What are polypeptides examples?Peptides act as structural components of cells and tissues, hormones, toxins, antibiotics, and enzymes. Examples of peptides i...
The use of RNA-sequencing has garnered much attention in the recent years for characterizing and understanding various biological systems. However, it remains a major challenge to gain insights from...
RNA-Seq based transcriptome assembly has become a fundamental technique for studying expressed mRNAs (i.e ., transcripts or isoforms) in a cell using high-throughput sequencing technologies, and is serving as a basis to analyze the structural and quantitative differences of expressed isoforms between samples. However, the current transcriptome assembly algorithms are not specifically designed to handle
Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.
While the actual health risks of cell phones remain unquantifiable, they most certainly exist. You can & should reduce your exposures.
Methods used to sequence the transcriptome often produce more than 200 million short sequences. Researchers at Johns Hopkins University have developed StringTie, a computational method that applies a network flow algorithm originally developed in optimization theory, together with optional de novo assembly, to assemble these complex data sets into transcripts. When used to analyze both
The DNA code is the means by which life communicates. The DNA code contains instructions for creating a living entity. The DNA Code Worksheet is an excellent resource for kids interested in learning about the structure and function of DNA. This interesting game is ideal for biology students seeking a thorough understanding of genetics and cellular processes.
One of the more popular arguments used for humans supposedly evolving from apes is known as the chromosome fusion. The impetus for this concept is the evolutionary problem that apes have an extra pair of chromosomes—humans have 46 while apes have 48. If humans evolved from an ape-like creature only three to six million years ago, a mere blip in the grand scheme of the evolutionary story, why do humans and apes have this discrepancy? The evolutionary solution proposes that an end-to-end

RNA-Seq is a powerful tool used to obtain in-depth information on expression profiling, gene annotation, and transcript discovery. With the growing popularity of RNA sequencing, new library preparation techniques are becoming commercially available. These techniques are improvements on the classic poly-A selection and rRNA reduction methods, and in some cases sensitive enough to analyze the
