What is Pyrophosphate Sequencing (Pyrosequencing)?

Pyrophosphate sequencing represents an innovative enzymatic cascade chemiluminescence sequencing method driven by four key enzymes: DNA polymerase, ATP sulfurylase, luciferase, and adenosine triphosphate bisphosphatase (apyrase). This cutting-edge technology enables real-time detection of biological light signals emitted during DNA synthesis, setting a groundbreaking precedent for simultaneous sequencing and synthesis. In the realm of early tumor screening […]

Fact Sheet: Introns and Exons

What is Exon? A coding sequence within a fragmented gene, an exon (expressed region) constitutes a vital segment of a eukaryotic gene. It remains conserved post-splicing and serves as the basis for protein expression during protein biosynthesis. These nucleotide sequences are present in both the initial transcription product and the mature RNA molecule. Genome encompasses […]

8 Methods of Population Genetic Analysis

The study of population evolution relies on advanced genomic techniques like whole-genome resequencing or other sequencing methods. These technologies enable the acquisition of genomic data from diverse subpopulations within a species. By extracting extensive variant information such as single nucleotide polymorphisms (SNP), insertions/deletions (InDel), structural variations (SV), and copy number variations (CNV), researchers delve into […]

T-DNA Insertion Analysis in Agrobacterium-Mediated Transformation (AMT)

What is Agrobacterium-Mediated Plant Transformation? Agrobacterium, a soil-dwelling bacterium, can chemotactically infect a wide array of dicotyledonous plants. Exploiting wounded areas of the plant, Agrobacterium induces the formation of crown gall tumors or hairy roots. Within Agrobacterium‘s Ti and Ri plasmids resides a crucial fragment of transfer DNA known as T-DNA. This T-DNA has the remarkable capability […]

Human Leukocyte Antigen Molecules and HLA Typing

Overview of HLA Human leukocyte antigen (HLA) molecules are essential components of the immune system, playing a crucial role in activating antitumor immune responses through their interactions with T cell receptors (TCRs). HLA molecules are a class of glycoproteins composed of an alpha-heavy chain and a beta-light chain that are non-covalently bound. The structure of […]

Unlocking the Secrets of Neonatal Genomes: Insights from the BabySeq Project

Ten years ago, clinicians at several hospitals across the United States began sequencing the genomes of seemingly healthy infants in an attempt to understand how this technology would be able to detect recessive genetic disorders that would not be detected by conventional newborn blood tests. Recently, a team of researchers from BabySeq, the world’s first […]

New Human Pan-Genome Draft: An Additional 119 Million Base Pairs To Better Reflect Human Diversity!

The result of the Human Genome Project is a recognized "standard" for scientists – the reference genome. Like a coordinate system, researchers can better understand the structure, function, and variation of the human genome against the reference genome. The Human Genome Project began in 1990, the working draft was published in 2001, and the final […]

The First T2T Genome of Grape Provides New Insights into Its Genetic Breeding and Evolutionary Studies

Since the first human genome was published in 2000, many reference genomes have been assembled successively in various species. However, the highly repetitive sequences (telomeric, mitotic, ribosomal DNA) clustered in the genome have resulted in many missing fragments in the assembled genomes. Fortunately, thanks to improvements in sequencing technologies and computational algorithms, a new era […]
