In 1977, Frederick Sanger and his team invented the chain termination DNA sequencing technology, namely Sanger sequencing technology, which opened a door for human beings to explore the genetic code of life and won the Nobel Prize again. Since its inception, Sanger sequencing technology has experienced a series of important development stages. In the early […]
Sanger sequencing, a classic DNA sequencing technology, has played an irreplaceable role in molecular biology research, clinical diagnosis, genotyping, and other fields, thanks to its high accuracy and reliability, since its introduction in the 1970s. Although high-throughput sequencing technology has been widely used, Sanger sequencing is still the core technology in many laboratories and research […]
Non-coding RNA (ncRNA) is a type of RNA molecule that does not have the ability to encode proteins and plays a vital role in gene regulatory networks. In the past, people believed that the main function of RNA was to serve as a bridge for information transmission between DNA and protein, but with the deepening […]
In the evolution of biotechnology applications, DNA extraction, a fundamental technology for analyzing genetic information, has consistently occupied a core and irreplaceable position. From the molecular verification of Mendel’s genetic factor hypothesis to the vast practice of the Human Genome Project, the acquisition of high-quality DNA constitutes the logical starting point for scientific discovery and […]
In the long exploration process of life science, the pursuit of the essence of genetic material has always been the core driving force for the development of the discipline. In the 19th century, Mendel discovered the laws of separation and free combination of genetic factors, starting with the pea hybridization experiment, which opened the scientific […]
In the regulatory network of the human immune system, the human leukocyte antigen (HLA) gene family, which encodes the major histocompatibility complex (MHC), plays a central role in regulating immune responses and the genetic susceptibility mechanisms of diseases. HLA molecules mediate adaptive immune response through antigen presentation mechanism, and allelic variation caused by its high […]
In the vast theatre of nature, microorganisms reign supreme as the oldest and most abundant life forms, holding a pivotal position. A question often arises: "Why do microorganisms in similar environments evolve differently?" The answer lies in the intricate and fascinating process of divergent evolution. Despite seemingly identical environmental conditions, microorganisms can evolve into populations […]
In biology science, transcription is the core biological process of transforming DNA genetic information into RNA and is the key link of gene expression regulation. Although both eukaryotes and prokaryotes rely on transcription to realize the transmission and expression of genetic information, due to the significant differences in cell structure, metabolic needs, and survival strategies, […]
Eukaryotic transcription is a key initial step of gene expression, and its precise regulation is important for maintaining cell homeostasis and normal physiological functions of organisms. In recent years, more and more studies show that the disorder of the transcription process is closely related to the occurrence and development of many human diseases. An in-depth […]
