关于生物信息学的论文摘要
这种最基本的东西没必要求论文啊，自己随便写写就好了，用个DNAMAN，随便挑个基因，分分钟搞出来。再者没人会拿这种东西单独去发一篇论文吧？这点东西根本不够资格，只够在某篇论文里的两句话的分量。再看看别人怎么说的。

生物信息学我有来头
林学与业，课程改革生物信息学，是一门综合学科。涉及到数学，生物学和计算机的内容。但在我看来，计算机的基础需要，但要求不是很高，关键是要有很好的生物学知识，包括遗传学的、生物化学的、发育生物学的、分子生物学的、植物生理学的知识等等，也就说需要达到这样的一个要求：在进行数据分析时，能对各种分析结果进行生物学的评价，并给出最优的分析策略。同时也应该有纯熟的数理基础，包括统计学的、拓扑学的，这样才能把待分析的问题转换成可计算的模型，最后能给出实现的程序。从个人来说，因为生物信息学是一个非常大的领域，所以，关键是要确定自己的研究方向。比如，以关联分析为方向的生物信息学，那么就要掌握好各种关联分析的统计分析方法，有很强的数据管理能力，足够好的序列分析能力（这是进行variation查找和分析的基础）
生物类的呗，医学类的呗，都是可以的，还可以看下在生物医学期刊上
空手套白狼，实现有难度。你要熟悉各种生物的基因组，要分析能力很强才行。
生物信息相关论文
最好先阅读几篇相应文章和相今似的论文，比如你的课题是油菜，你可以搜有关其他物种如小麦的。根据论文写作步骤制定实验计划。要练习使用一些常用软件，如NCBI,GenBank,在用时最好先下载安装有道词典，因为是英文网站，不容易懂，专业名词也太多！不要怕，万事开头难！好好准备，入了门就好了！
谁一个、、论文不才交么……生物信息在生物学研究中的作用。生物信息是指生物体中包含的全部信息，如基因组信息、蛋白质、核酸、糖类等生物大分子的结构等。生物信息对生物体的生存、繁殖都起着重要作用。生物信息包含的范围很广，除遗传物质、神经电冲动和激素之外，生物体发出的声音、气味、颜色以及生物的行为本身都含有信息，都对生物的个体和群体产生影响，和生物的生存与进化密不可分。生物信息的特点是消耗极少的能量和物质即可产生极大的生物效应。生物信息一般可分为遗传信息、神经和感觉信息及化学信息。虽然遗传信息和神经感觉信息的载体都属于化学物质，但通常所指的化学信息是除以上两类物质以外的化学物质所携带和传递的信息。高等生物的激素及昆虫外激素都属于这一类。遗传信息是指生物为复制与自己相同的东西、由亲代传递给子代、或各细胞每次分裂时由细胞传递给细胞的信息, 即碱基对的排列顺序(或指DNA分子的脱氧核苷酸的排列顺序） 。遗传信息以密码形式存储在DNA分子上，通过DNA的复制传递给子代。在后代生长发育过程中，遗传信息自DNA转录给RNA，后翻译成特异的蛋白质，以执行各种生命功能。从历史上看，首先是由GJMendel（1866）的研究形成了概念，即相应于生物各种性状的因素（现在称为基因）中包含着相应的信息（以后GBeadle等人（1941）所开创了遗传生物化学的研究，描绘出这样一个轮廓：基因和决定生物结构与功能的蛋白质之间具有一对一的对应关系。 关于基因的化学本质方面，根据OTAvery等（1944）进行的转化实验，以及AHershey和MChase（1952）用大肠杆菌噬菌体的DNA进行的性状表达实验，已阐明DNA是遗传信息的载体。附着DNA结构研究的进展，现在已经确立了这样的概念，即基因所具有的信息可将DNA的碱基排列进行符号化。信息在表达时，DNA的碱基排列首先被转录成RNA的碱基排列，然后再根据这种排列合成蛋白质。有的病毒的遗传信息的载体不是DNA，而是RNA。遗传信息不仅有相应于蛋白质的基因信息，也包括对信息解读所必需的信息、控制信息表达所必需的信息，以及生物为了复制与自己相同结构所必需的一切信息。神经和感觉信息靠电脉冲和神经递质携带和传递。神经系统接受内外环境中的信息，进行加工处理，调节和控制机体各部分功能。生物靠神经系统电脉冲和神经递质携带和传递。神经系统的功能是接收、传递内外环境中的信息，加以处理、分析,从而控制和调节机体各部功能,对环境作出适当的反应。因此，神经信息对于有机体的生存以及正常生活起着至关重要的作用。化学信息是除上述两类物质外由化学介质传递的信息。生物体的各种功能能够有条不紊地进行，对环境能及时做出反应，是由于生物体内存在着通过各种各样的化学信息分子进行传递的信息系统。生物信息在生物研究中有重要作用，然而，原始的生物信息资源挖掘出来后，生命科学工作者面临着严峻的挑战：数以亿计的ACGT序列中包涵着什么信息？基因组中的这些信息怎样控制有机体的发育？基因组本身又是怎样进化的？生物信息学产业的高级阶段体现于此，人类从此进入了以生物信息学为中心的后基因组时代。结合生物信息学的新药创新工程即是这一阶段的典型应用。因此，生物信息学便是生物信息在生物研究中重要应用。 生物信息学是在生命科学的研究中，以计算机为工具对生物信息进行储存、检索和分析的科学。生物信息学研究对象是生物信息。其研究重点主要体现在基因组学和蛋白学两方面，具体说就是从核酸和蛋白质序列出发，分析序列中表达的结构功能的生物信息。 具体而言，生物信息学作为一门新的学科领域，它是把基因组DNA序列信息分析作为源头，在获得蛋白质编码区的信息后进行蛋白质空间结构模拟和预测，然后依据特定蛋白质的功能进行必要的药物设计。基因组信息学,蛋白质空间结构模拟以及药物设计构成了生物信息学的3个重要组成部分。从生物信息学研究的具体内容上看，生物信息学应包括这3个主要部分：(1)新算法和统计学方法研究；(2)各类数据的分析和解释；(3)研制有效利用和管理数据新工具。 生物信息学作为基因组研究的有力武器，被广泛地用来加快新基因的寻找过程，以达到将“有用”新基因抢先注册专利的目的。在这场世界范围内的竞争中，中国科学家以及科研资金投向的决策部门如何结合我国科研水平的现状、优势领域等客观情况将有限的投资投入以求获得最大可能的科学研究以及商业回报，是一个无法回避的新课题。 生物信息学的主要研究方向： 基因组学 - 蛋白质组学 - 系统生物学 - 比较基因组学，随着包括人类基因组计划在内的生物基因组测序工程的里程碑式的进展，由此产生的包括生物体生老病死的生物数据以前所未有的速度递增，目前已达到每14个月翻一番的速度。同时随着互联网的普及，数以百计的生物学数据库如雨后春笋般迅速出现和成长。然而这些仅仅是原始生物信息的获取，是生物信息学产业发展的初组阶段，这一阶段的生物信息学企业大都以出售生物数据库为生。以人类基因组测序而闻名的塞莱拉公司即是这一阶段的成功代表。 综上所述,对生物信息的研究对生物学的蓬勃发展具有重要作用。
