Overview of Ribosomal RNA (rRNA)

What is ribosomal RNA? Ribosomal RNAs (rRNA) are the major components of ribosomes, which are responsible for protein synthesis by converting the instructions found in messenger RNA into the chains of amino acids. The key catalytic activity of ribosomes comes from the rRNAs. Additionally, rRNAs play an active role in recognizing conserved portions of mRNAs […]

Fact Sheet: Single Nucleotide Polymorphisms (SNPs)

What are SNPs? Single nucleotide polymorphisms, commonly called SNPs (pronounced “snips”), are the most frequent type of genetic variation among people, accounting for more than 90% of all differences between unrelated individuals. A SNP represents a difference in a single nucleotide. The DNA sequence contains four types of nucleotide bases: A (adenine), C (cytosine), G […]

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 […]

Integrative Genomic and Transcriptomic Analysis of Immunotherapy in Advanced NSCLC Using WES and RNA-seq

The use of PD-1/PD-L1 inhibitors has significantly improved overall survival in a subset of non-small cell lung cancer (NSCLC) patients, but only about 20% of patients respond to treatment. Identifying predictors of response is crucial to improve patient selection for immunotherapy. However, current understanding of relevant predictors is limited by the lack of large, multi-omic […]

Difference between genotyping and DNA sequencing

In the realm of molecular biology research, there exist two oft-confounded methodologies used with regularity: genotyping and DNA sequencing. Despite their seeming synonymy, these methods differ considerably regarding their impact on research outcomes and applications. This blog post endeavors to elucidate the contrasts between genotyping and DNA sequencing, while exploring their respective benefits and drawbacks. […]

How Does PacBio SMRT Sequencing facilitate AAV Vector Development?

Recombinant adeno-associated virus (AAV) has emerged as one of the primary vectors for gene therapy. This is because it has many desirable properties, including lack of pathogenicity, efficient infection of dividing and non-dividing cells, and sustained maintenance of the viral genome. With an excellent safety profile in numerous preclinical studies and hundreds of clinical trials […]

How to Sequence Chloroplast Genome and Why?

Introduction As one of the organelles that contain their own genome, chloroplasts (cp) are plastids with double membranes and vesicle-like structures. These tiny organelles convert solar energy, synthesize organic matters, and feed almost the entire life on Earth while providing for their own needs. However, it seems that chloroplasts are not satisfied with this, as […]

Genome Sequencing Drives Progress in Mitochondrial Diseases Research

Mitochondrial diseases (MitD) are an important clinical or medical challenge. Research has shown that genome sequencing can help to enhance the understanding of the genetic causes of MitD and to accelerate the development of functional research, clinical tests and therapeutic tools. What is Mitochondrial Disease? Mitochondria are membrane-bound organelles found in most eukaryotic cells that […]

RNA Sequencing for The Analysis of Exosome Transcriptome

Introduction to Exosomes Exosomes are small extracellular vesicles (EVs), ranging from 30 to 100 nm in diameter, carrying heterogeneous cargo, including miRNA, mRNA, lncRNA, lipids, and proteins. Exosomes widely present in very large quantities in all eukaryotic cells, mediating intercellular communication after being released into the extracellular space. In humans, exosomes nearly exist in all […]
