American Scientists' New Developments in Drosophila Genome Research

Scientists from NASA and scientists from Yale University, Columbia University, and Amsterdam University collaborated to study DNA coding structures that control basic biological functions. This study will change human understanding of the disease. They found that genes have changed at every major stage in the life cycle of organisms. Scientists used the fruit fly to make a special gene expression map for graduate students to change under the influence of microgravity and radiation. Dr. Viktor Stolc, head of NASA's Ames Center for Genome Research, said: "Drosophila is a very important tool for studying human diseases and biological evolution." The researchers used advanced technology to put a section of all genes in Drosophila. The DNA fragments were placed on slides to determine RNA expression. The results of this study have been published in Science. The paper presents a complete, non-repetitive genome expression map and reveals a richer and more variable RNA expression sequence than previously predicted. At the same time, the paper also lists a complete record of active gene expression in Drosophila. It has never been studied in this area before. Therefore, it is an important step to fully understand gene expression in flight. It will help us better understand The influence of microgravity on human health and growth will also help NASA ensure that astronauts can remain in normal conditions during long-time outbound space exploration flights. The Drosophila RNA expression level measures the growth and development of each gene from egg to adult at each stage. The results of the study paint a detailed map of gene expression activity, including some of the previously unclear parts of the Drosophila genome. Stolc said: "According to the results of the research, we have a comprehensive understanding of the active gene expression in Drosophila's growth and development, which will have an impact on the future analysis of all genetic material in living cells."
