Recently, Chinese scientists from Tianjin University, Tsinghua University, and Huada Gene have made major breakthroughs in eukaryotic genome design and chemical synthesis. They completed the de novo design and chemical synthesis of the chromosomes of four eukaryotic Saccharomyces cerevisiae, breaking the boundary between non-living matter and life, and opening the process of “designing life, recreating life and reshaping lifeâ€. Breaking through the problem of cell dystolysis caused by synthetic genomes, designing a chromosome-forming disease model and developing a long-chromosome hierarchical assembly strategy, demonstrating that artificially designed and synthesized genomes have the flexibility to increase and eliminate them... These studies have formed 4 The paper was published on the cover of the world's top academic journal Science in March 10th. Genetically modified yeast has been used to make vaccines, drugs, and specific compounds. The publication of these new results means that chemical design of custom yeast organisms is possible and the range of products will be expanded.
Synthetic biology is the third biotechnological revolution marked by genome design and synthesis following the “DNA double helix discovery†and “human genome sequencing projectâ€. The Saccharomyces Cerevisiae Gene Combination Program (Sc2.0 Program) is a landmark international collaborative project for synthetic genomics research. The project was initiated by Jeff Berke, a member of the American Academy of Sciences, and is a multi-country research institute that works and collaborates to design and chemically recreate the complete S. cerevisiae genome.
The largest divisions in the biological world are not plants and animals, nor multicellular and single-celled organisms, but are distinguished by prokaryotes and eukaryotes. The genome of prokaryotes is relatively simple, while the DNA of eukaryotes such as animals, plants, and fungi is both rich and complex. At the same time, genetic material DNA is usually distributed to different chromosomes, which are deep in specific regions of the nucleus. Therefore, synthesizing the genome of a eukaryote is a very difficult task. But if biology truly leads the technological revolution, synthetic eukaryotic genome technology will play a very central role.
Water Test Strips 15 Parameters
Detection method:
visual
Operation method:
1. Visual inspection: Immerse the test area of the test paper into the fully stirred fresh drinking water, and take it out immediately;
2. Put the edge of the strip against the edge of the container to remove excess water samples;
3. Compare the test strip with the colorimetric table on the bottle label, and record the test result in the determination time: 0 ~ 60 seconds. Use visual.
Storage conditions:
The test paper should be stored in room temperature, dry environment, away from a variety of chemical reagent environment, avoid direct sunlight. This product does not need to be refrigerated (if it is stored for a long time, it should be restored to room temperature and opened for use).
