How to Study Population Evolution by Genome Sequencing?

Introduction to Population Evolution A population, also known as a species, is a group of individuals who can all interbreed. The collection of these genes is known as a gene pool because these individuals can share genes and pass on combinations of genes to the next generation. Only populations, not individuals, go through the evolutionary […]

Sequencing Technologies and Applications in Microecology Research

Organisms live in an ecological context, and pure cultures rarely exist in nature. Microbial communities comprising microecology are one example of systems that are far from being pure culture which makes them dynamic in playing roles in the ecosystem.  Despite their abundance and ubiquity, our understanding of microecology, their interactions, and functions lag our knowledge […]

Epigenetics Sequencing Methods for Bacterial Methylation Sequencing

DNA methylation, histone variant, histone modifications, and nucleosome positioning are pathways for epigenetic regulation in eukaryotes. Bacteria, on the other hand, lack histones and nucleosomes; hence, they primarily use DNA methylation as their epigenetic gene regulation. There are three different types of DNA methylation in bacterial genomes: N4-methylcytosine (4mC), N6-methyladenine (6mA), and 5-methylcytosine (5mC). The […]

Fecal Microbiome Research: From Sampling to Sequencing

In recent years, studies have been progressively conducted to assess the effect of distinct sampling techniques on the outcomes of fecal microbiome assessment, in order to address this unmet need in the area of microbiome research. These methodology researches are useful for researchers to create quite rational guidelines for the procedure of fecal sampling, handling, […]

Viral Genome Sequencing: Reference Sequence and Variant Analysis of SARS-COV-2

Introduction to SARS-COV-2 In December 2019, the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started and has enveloped the world in an unparalleled global pandemic. The clinical features of COVID-19 patients are comparable during the 2002-2003 outbreak of SARS-CoV-1, which caused more than 8,000 cases reported and about 800 deaths. As such, human SARS-CoV-2 […]

Efficient, Accurate, and Affordable, NGS Offers Great Choice for Antibiotic Gene Resistance

When bacteria, fungi, viruses, and parasites change over time and no longer respond to antibiotics, antimicrobial resistance (AMR) occurs. This makes an emerging issue related to the development and usage of antibiotics. Traditional microbial screening methods for AMR can be very laborious and time-consuming. However, the use of next-generation sequencing (NGS), especially whole-genome sequencing (WGS), […]

The Applications and Methods of Next-Generation Sequencing of SARS-CoV-2 on COVID-19 Research

Without previous understanding of organisms, next-generation sequencing (NGS) offers an efficient unbiased approach to determine new coronavirus strains and other pathogens. New variants of the SARS-CoV-2 coronavirus are increasingly concerned about the rapid spread, highlighting the necessity for more sequencing to rapidly identify mutations and limit the risk of new strains. Sequencing was employed early […]

Data Quality Control of High-Throughput Sequencing: Importance and Protocols

The most powerful approach to scan for unspecific germline variations, somatic mutations, and structural variants is high-throughput sequencing. Whole-genome sequencing, exome sequencing, and targeted region sequencing are three of the most common sequencing concepts in DNA sequencing. While highly useful, in different aspects of data collection, computation time, and variant detection precision, sequencing data creates […]

Why Do We Study lncRNA? The Formerly Regarded “Transcriptional Junk” Sheds Light on Disease Research

Determining an appropriate treatment through precision medicine requires inspection of crucial novel biomarkers from tissue samples or liquid biopsies such as plasma/serum, sputum, saliva, urine, and cerebrospinal fluid for earlier disease diagnosis and prognosis. Analysis of non-coding RNA such as microRNA (miRNA) and long noncoding RNA (lncRNA), DNA methylation, and posttranslational histone modifications are epigenetic […]

CRISPR Screen Sequencing, An Innovative Sequencing Technology that Can Facilitate COVID-19 Research

Clustered regularly interspaced short palindromic repeats, or CRISPR, is one of the most phenomenal discoveries that paved the way for modern genome screening and editing technologies. CRISPR is a family of DNA found in the genome of prokaryotes, specifically bacteria and archaea. These sequences contain DNA fragments from known bacteriophages that infect the particular prokaryote.
