What is The Role of RNA m6A Methylation

RNA modifications, notably N6-methyladenosine (m6A) methylation, have risen to prominence as pivotal orchestrators of gene expression and cellular dynamics. Within this array of modifications, the m6A methylation of RNA, especially within messenger RNA (mRNA) transcripts, has garnered considerable interest due to its profound involvement in diverse biological phenomena and the onset of pathological conditions. In […]

Introduce to 16S rRNA and 16S rRNA Sequencing

What Is 16S rRNA? The 16S rRNA (16S ribosomal RNA) is a constituent component of the 30S subunit in prokaryotic ribosomes. The “S” in 16S pertains to the Svedberg unit, a measure that reflects the sedimentation rate of large molecules in a centrifugal field – the higher the value, the larger the molecule. The 16S rRNA gene […]

Primer Walking Sequencing vs Shotgun Sequencing: A Comprehensive Comparison

In the field of genomics, two notable methodologies for DNA sequencing have risen to prominence: Primer Walking Sequencing and Shotgun Sequencing. These techniques, although distinct in their approaches, stand as indispensable instruments for deciphering the intricacies inherent within the genetic code. This discourse endeavors to dissect the nuances of both methodologies, elucidating their fundamental principles, […]

Exploring Small RNA: Types, Functions, Regulation, and Sequencing

The vital roles played by small RNA molecules in gene regulation and a myriad of cellular processes are undeniably essential within the realms of biological sciences. This extensive review encompasses a deep exploration into the complex nature of small RNA. We examine its definition, the diversity of its types, its multifaceted functions, as well as […]

Advancements in DNA Methylation Detection: From Bisulfite Treatment to Cutting-Edge Chip Technologies

1992 Bisulfite Treatment for Methylation Samples Commonly referred to as BS conversion, it involves treating methylated samples with bisulfite (abbreviated as "BS"), where "conversion" refers to the process by which unmethylated cytosines (C) are converted to uracils (U) and eventually to thymines (T) through PCR amplification, while methylated cytosines (5mC) are preserved. 2003 Pyrosequencing Pyrosequencing […]

Fact Sheet: Illumina Complete Long-Read Sequencing

In the realm of modern biology, unlocking the complexities of genomes has been significantly propelled by next-generation sequencing (NGS) technologies. Among these, the sequencing-by-synthesis (SBS) chemistry, in tandem with the esteemed DRAGEN Bio-IT platform, stands out for its unparalleled accuracy in delivering whole genome sequencing (WGS) data. However, the quest for understanding the entirety of […]

Fact Sheet: Ribosomal RNA (rRNA)

What is rRNA? Ribosomal RNA (rRNA) serves as the foundational framework of the ribosome, a vital organelle orchestrating protein synthesis. Unlike messenger RNA (mRNA), which carries genetic instructions for protein assembly, rRNA is a non-coding RNA that facilitates the actual process within the ribosome. Derived from ribosomal DNA (rDNA), rRNA collaborates with ribosomal proteins to construct […]

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 […]
