Eukaryotic transcription is a key initial step of gene expression, which occupies a core position in the central rule. It uses DNA as a template to synthesize various RNA molecules by RNA polymerase. Its regulatory network is fine and complex, and it is widely involved in life activities such as embryonic development, cell differentiation, and […]
Variant Calling Format (VCF) is a standardized text file format widely used in bioinformatics and genomics to store and exchange genetic variation information. Researchers and clinicians depend on this standardized approach when analyzing differences in DNA sequences across populations or individuals. The importance of this format extends across multiple domains of genetic research and personalized […]
In gene medicine, variant analysis helps doctors turn DNA data into useful health insights. The process starts by filtering out common gene changes using databases like gnomAD. Then, tools like CADD and REVEL predict if the remaining variants might cause problems. Other tools, such as SIFT and PolyPhen-2, check for protein damage, while SpliceAI finds […]
In the vast human genome, variations are everywhere. Each person’s genome carries millions of small differences in sites. These genomic variations not only shape physiological differences and disease susceptibility between individuals, but also profoundly affect the evolution of mankind. With the rapid development of genomics and high-throughput sequencing technology, scientists are able to more systematically […]
In the field of modern biology science, the continuous innovation of molecular biology technology promotes the exploration of gene function and regulation mechanism. As a synthetic DNA sequence, complementary DNA (cDNA) originated from the reverse transcription process of messenger RNA (mRNA), and has played an indispensable core role in many frontier research fields such as […]
In the field of molecular biology, complementary DNA (cDNA) and genomic DNA (gDNA) are two crucial concepts, which play a key role in life science research, biotechnology application and many other aspects. Although both of them are related to the transmission and interpretation of genetic information, there are significant differences in structure, function and acquisition […]
In the deep exploration of contemporary molecular biology, complementary DNA (cDNA) has become the core factor to promote the development of multi-dimensional research with its excellent characteristics. With the deepening study of gene expression regulatory network, functional genomics framework and molecular pathological mechanism of diseases, the limitations of traditional research strategies in the face of […]
Fungi are a kind of magical creatures. They are in various forms, from microscopic yeasts to mushrooms and fungus visible to the naked eye. It is not only different from the photosynthesis of plants, but also different from the feeding mode of animals. It survives by absorbing nutrients from the surrounding environment. Widely distributed in […]
Eubacteria belong to the prokaryotic domain, with prokaryotic cell structure, nuclear wrapped by nuclear membrane, and genetic material DNA exposed in the quasi-nuclear region. Binary fission is the main breeding mode, and some of them can form spores to resist adversity in harsh environment. Metabolic types are diverse, including photoautotrophic, chemoautotrophic, photoheterotrophic and chemoheterotrophic. Respiratory […]
Eubacteria, as an ancient and diverse microbial group on the earth, are widely distributed in every corner of our lives. From hot springs to cold polar regions, from fertile soil to deep oceans, there are traces of them. Although this kind of prokaryote is small, it occupies an irreplaceable key position in the operation of […]
