Degradome sequencing, also known as parallel analysis of RNA ends (PARE) sequencing, is a cutting-edge technique that leverages high-throughput sequencing and bioinformatics to investigate the degradation products of mRNA. This method is particularly valuable for identifying the target genes regulated by microRNAs (miRNAs), which are small, endogenous non-coding RNAs approximately 22 nucleotides in length. miRNAs play crucial

In the quest to unravel the complexities of infectious diseases, understanding the intricate interplay between pathogens and their hosts is paramount. This requires a comprehensive analysis of gene expression and the regulatory mechanisms at play during infection. Traditional RNA sequencing (RNA-seq) has long been employed to investigate the gene expression profiles of microbial pathogens. However, recent advancements in RNA-seq technologies have introduced innovative methods that delve deepe

Operational Taxonomic Units (OTUs) serve as fundamental units in the realm of numerical taxonomy, particularly in the study of microbial ecology. These units can represent various biological classifications, including individuals, species, genera, or even higher taxonomic levels. The term "operational taxonomic unit" was introduced to address the discrepancies between traditional taxonomic classifications and the units used in numerical methods, which often lack comparability. This distinctio

The advent of next-generation sequencing (NGS) has revolutionized the field of microbiome research, particularly through the analysis of 16S rRNA gene sequencing. This technique allows for a comprehensive understanding of microbial communities, providing insights into their composition and functional potential. This article outlines best practices for the bioinformatics analysis of 16S rRNA sequencing, emphasizing the critical stages of data preprocessing and quantification.

When a ribosome is affixed to the polypeptide (protein) it is making, the ribosome-nascent chain complex (RNC) is the compilation of molecules that make up the ribosome. One of several methods can be used to halt the synthesis of the nascent polypeptide. RNCs are made and purified in labs to study the dynamics, biochemistry, folding, and interactions that the ribosome and proteins undergoing synthesis.

The ribosome, as a critical part of the central dogma, is a no

In recent years, the landscape of sequencing technologies has undergone a transformative shift, transitioning from research settings to the realm of clinical laboratories. This transformation has been catalyzed by rapid technological advancements and significant cost reductions. Despite a multitude of microorganisms known to inflict human infections, prevailing diagnostic techniques merely scratch the surface, leaving a vast array of pathogens unidentified. This persistent challenge i

What is sequencing depth and coverage?

Sequencing Depth

Sequencing depth is the ratio of the total number of bases (bp) obtained by sequencing to the genome size, which is one of the indicators to evaluate the sequencing volume. There is a positive correlation between sequencing depth and genome coverage, and the error rate or false positive results from sequencing decreases as the sequencing depth increases. For resequenced individuals, if a double-end or Mate

Analysis of variance (ANOVA) is a powerful statistical method that allows researchers to compare the means of two or more groups and determine if they are significantly different. It is a popular tool for testing hypotheses in a variety of fields in biology, including ecology, genetics, physiology, and biochemistry. In this article, we will explore how to choose the right type of ANOVA for your research question an

Submission of sequence data to NCBI archives

Next-generation sequencing, PacBio SMRT sequencing, and Nanopore sequencing, can generate numerous sequence data in a single run. Raw reads or assembled sequence need to be submitted to public sequence repository (DDBJ/ENA/GenBank - INSDC), which is required by the overwhelming majority

What Is RNA Splicing?

RNA splicing is a post-transcriptional modification process that occurs in eukaryotic cells. When a gene is transcribed, the initial RNA product is called pre-mRNA, which contains both coding regions (exons) and non-coding regions (introns). RNA splicing removes the introns from the pre-mRNA molecule and joins together the exons to form a mature mRNA molecule that can be translated into protein.

What Is the Process of RNA Splicing?
