生物信息学英文介绍Introduction to Bioinformatics.Bioinformatics is an interdisciplinary field that combines biology, computer science, mathematics, statistics, and other disciplines to analyze and interpret biological data. At its core, bioinformatics leverages computational tools and algorithms to process, manage, and minebiological information, enabling a deeper understanding of the molecular basis of life and its diverse phenomena.The field of bioinformatics has exploded in recent years, driven by the exponential growth of biological data generated by high-throughput sequencing technologies, proteomics, genomics, and other omics approaches. This data deluge has presented both challenges and opportunities for researchers. On one hand, the sheer volume and complexityof the data require sophisticated computational methods for analysis. On the other hand, the wealth of information contained within these data holds the promise oftransformative insights into the functions, interactions, and evolution of biological systems.The core tasks of bioinformatics encompass genome annotation, sequence alignment and comparison, gene expression analysis, protein structure prediction and function annotation, and the integration of multi-omic data. These tasks require a range of computational tools and algorithms, often developed by bioinformatics experts in collaboration with biologists and other researchers.Genome annotation, for example, involves the identification of genes and other genetic elements within a genome and the prediction of their functions. This process involves the use of bioinformatics algorithms to identify protein-coding genes, non-coding RNAs, and regulatory elements based on sequence patterns and other features. The resulting annotations provide a foundation forunderstanding the genetic basis of traits and diseases.Sequence alignment and comparison are crucial for understanding the evolutionary relationships betweenspecies and for identifying conserved regions within genomes. Bioinformatics algorithms, such as BLAST and multiple sequence alignment tools, are widely used for these purposes. These algorithms enable researchers to compare sequences quickly and accurately, revealing patterns of conservation and divergence that inform our understanding of biological diversity and function.Gene expression analysis is another key area of bioinformatics. It involves the quantification of thelevels of mRNAs, proteins, and other molecules within cells and tissues, and the interpretation of these data to understand the regulation of gene expression and its impact on cellular phenotypes. Bioinformatics tools and algorithms are essential for processing and analyzing the vast amounts of data generated by high-throughput sequencing and other experimental techniques.Protein structure prediction and function annotation are also important areas of bioinformatics. The structure of a protein determines its function, and bioinformatics methods can help predict the three-dimensional structure ofa protein based on its amino acid sequence. These predictions can then be used to infer the protein'sfunction and to understand how it interacts with other molecules within the cell.The integration of multi-omic data is a rapidly emerging area of bioinformatics. It involves theintegration and analysis of data from different omics platforms, such as genomics, transcriptomics, proteomics, and metabolomics. This approach enables researchers to understand the interconnectedness of different biological processes and to identify complex relationships between genes, proteins, and metabolites.In addition to these core tasks, bioinformatics also plays a crucial role in translational research and personalized medicine. It enables the identification of disease-associated genes and the development of targeted therapeutics. By analyzing genetic and other biological data from patients, bioinformatics can help predict disease outcomes and guide treatment decisions.The future of bioinformatics is bright. With the continued development of high-throughput sequencing technologies and other omics approaches, the amount of biological data available for analysis will continue to grow. This will drive the need for more sophisticated computational methods and algorithms to process and interpret these data. At the same time, the integration of bioinformatics with other disciplines, such as artificial intelligence and machine learning, will open up new possibilities for understanding the complex systems that underlie life.In conclusion, bioinformatics is an essential field for understanding the molecular basis of life and its diverse phenomena. It leverages computational tools and algorithms to process, manage, and mine biological information, enabling a deeper understanding of the functions, interactions, and evolution of biological systems. As the amount of biological data continues to grow, the role of bioinformatics in research and medicine will become increasingly important.。

生物信息学简介一. 生物信息学诞生的历史必然性生物信息学(Bioinformatics)就其萌生而言,是一门相当古老的学科,因为早在计算机初创期的1956年就已经在美国田纳西州的Gatlinburg召开过首次“生物学中的信息理论讨论会”;而就其发展而言,却是一门相当年轻的学科,因为继20余年的沉默之后,只有伴随着八九十年代计算机技术的迅猛发展,它才同时得以获得自身的大发展。
无论从理论上来讲还是从现实情况来看,生物信息学的实质就是利用计算机科学和网络技术来解决生物学问题。
它的诞生和发展是应时所需,是历史的必然,已经悄然渗透到生物科学的每一个角落,以至人们在意识到它的存在之前就已经离不开它了!二十世纪尤其是末期,生物科学技术的迅猛发展,无论从数量上还是从质量上,都极大地丰富了生物科学的数据资源,数据资源的急剧膨胀首先迫使我们不得不考虑寻求一种强有力的工具去组织他们,以利于对已知生物学知识的储存和进一步加工利用。
大量多样化的生物学数据资源中必然蕴含着大量重要的生物学规律,这些规律是我们解决许多生命之谜的关键所在,然而继续沿用传统手段以人脑来分析如此庞杂的数据实在是太勉为其难了!人们同样需要寻求一种强有力的工具去协助人脑完成这些分析工作。
可以说,伴随着二十一世纪的到来,生物科学的重点和潜在的突破点已经由二十世纪的试验分析和数据积累转移到数据分析及其指导下的试验验证上来,生物科学也正在经历着一个从分析还原思维到系统整合思维的转变。
那么,我们所寻求的那种强有力的数据处理分析工具就成为未来生物科学的关键所在;似乎是上帝的恩赐,伴随着生物科学这一需求的加剧,以数据处理分析为本质的计算机科学技术和网络技术同样获得了突飞猛进的进展,自然就成为生物科学家的必然选择,计算机科学技术和网络技术日益渗透到生物科学的方方面面,一门崭新的、正是如火如荼的、拥有巨大发展潜力的生物信息学也就悄然而坚定地发展和成熟起来了!可以说,历史必然性的选择了生物信息学——生物科学与计算科学的融合体——作为下一代生物科学研究的重要工具。
一.什么是生物信息学?Genome informatics is a scientific discipline that encompasses all aspects of genome information acquisition, processing, storage, distribution, analysis, and interpretation. (它是一个学科领域,包含着基因组信息的获取、处理、存储、分配、分析和解释的所有方面。
)(The U.S. Human Genome Project: The First Five Y ears FY 1991-1995, by NIH and DOE)生物信息学是把基因组DNA序列信息分析作为源头,破译隐藏在DNA序列中的遗传语言,特别是非编码区的实质;同时在发现了新基因信息之后进行蛋白质空间结构模拟和预测。
生物信息学的研究目标是揭示“基因组信息结构的复杂性及遗传语言的根本规律”。
它是本世纪自然科学和技术科学领域中“基因组、“信息结构”和“复杂性”这三个重大科学问题的有机结合。
How to find the coding regions in rude DNA sequence?By signals or By contentsAmong the types of functional sites in genomic DNA that researchers have sought to recognize are splice sites, start and stop codons, branch points, promoters and terminators of transcription, polyadenylation sites, ribosomal binding sites, topoisomerase II binding sites, topoisomerase I cleavage sites, and various transcription factor binding sites. Local sites such as these are called signals and methods for detecting them may be called signal sensors.二.新基因和新SNPs的发现与鉴定大部分新基因是靠理论方法预测出来的。
