高三生物错题重组(基因工程引物专练)
高中生物错题重组-引物专练题一、判断题（正确涂A，错误涂B，每题3分，共30分）1、光反应阶段的产物是NADH、ATP和O22、人体T细胞成熟的场所是骨髓，B细胞成熟的场所是胸腺。
3、体液免疫过程中，抗体和病毒结合后病毒最终被清除的方式是被吞噬细胞吞噬消化4、焙烤是为了利用高温杀死大麦种子胚并进行灭菌5、稀释涂布平板法和平板划线法均能得到单菌落，都可用于细菌计数6、在DNA粗提取与鉴定实验中，研磨后的离心是为了加速DNA的沉淀7、受精卵经体外培养后，细胞增殖至2细胞时，可进行胚胎移植8、通常作为核移植受体细胞的是去核的次级卵母细胞9、正常乳酸发酵时，会有部分醋酸菌繁殖，以致发酵液pH下降10、蛋白胨可为厌氧菌提供氮源以及供合成蛋白质必需的各种氨基酸二、单选题(每题3分，共30分)1．基因工程中PCR扩增产物一般通过琼脂糖凝胶电泳来鉴定。
下列关于PCR 及电泳鉴定的叙述，错误的是（）A．PCR通过调节温度来控制DNA 双链的解聚及模板与引物的结合B．PCR 反应的缓冲液中需同时添加Mg2+、引物、模板、Taq 酶等C．因DNA分子在凝胶载样缓冲液中带正电荷或负电荷，可用于电泳D．DNA分子的迁移速率与凝胶的浓度、DNA分子的构象等有关2．研究表明，DNA合成先要沿子链合成方向以DNA为模板合成引物，因为DNA聚合酶只能催化脱氧核苷酸加到已有核酸链的游离3’端羟基上，而不能使脱氧核苷酸自身发生聚合，如下图所示。
据图分析，下列关于图中“引物”的叙述正确的是（）A．是一小段单链DNA B．在DNA合成后期会被切除C．合成的方向为3’→5'D．合成时需DNA聚合酶的催化3．新冠疫情的快速控制，离不开我国政府的科学决策和对新冠病毒（一种RNA病毒）的快速检测能力。
荧光定量PCR可定量检测样本中DNA含量，其原理是在PCR反应体系中加入引物的同时，加入与某条模板链互补的荧光探针，当耐高温的DNA聚合酶催化子链延伸至探针处会水解探针并生成荧光分子，即DNA每扩增一次，就有一个荧光分子生成（如图），荧光监测系统随时接收荧光信号变化。
如何有效解决高三复习阶段的错题
如何有效解决高三复习阶段的错题高三是每个学生都经历的关键时期，复习阶段的错题是一个常见的问题。
如何有效解决高三复习阶段的错题是每个学生都需要掌握的技巧。
本文将介绍一些有效的方法来解决高三复习阶段的错题。
一、有效的错题整理方法在解决错题之前，首先需要进行错题的整理。
下面将介绍一些有效的错题整理方法。
1.建立错题本每个学生应该建立自己的错题本。
将每次做错的题目都写在错题本上，并留下正确解答。
这样可以方便学生随时翻阅错题，并复习正确解答，避免再次犯同样的错误。
2.分类整理错题将错题按照不同的科目、章节或题型进行分类整理。
这样可以让学生更加清晰地了解自己在哪个方面容易犯错，有针对性地进行复习。
3.标注难点和易错点在错题本上标注出易错点和难点，以便在后续的复习中重点关注这些内容。
这样可以帮助学生充分理解并消化这些知识点，避免再次犯错。
二、有针对性地解决错题整理好错题后，接下来是解决错题的过程。
下面将介绍一些有针对性的解决错题的方法。
1.查阅相关资料当碰到难题时，学生可以查阅相关的教材、辅导书籍或上网搜索相关知识点，寻找解答。
这样可以帮助学生理解错题的正确解法，并扩展自己的知识面。
2.请教老师或同学当学生遇到解答不出的问题时，可以向老师或同学请教。
老师和同学可能会提供不同的解题思路和方法，帮助学生更好地理解和解答错题。
3.掌握解题技巧对于某些常见的错题类型，学生可以掌握相应的解题技巧。
通过学习解题技巧，可以提高解题的准确性和效率，避免在相同的题型上再次出错。
三、定期复习错题解决错题不仅仅是一次性的过程，定期复习错题也是非常重要的一部分。
1.每周复习错题每周抽出固定的时间复习错题，巩固已经学过的知识，并且避免之前犯过的错误再次出现。
这样可以逐渐提高对知识点的掌握程度。
2.集中复习易错题对于那些易错题，应该加大复习的力度。
集中精力在这些题目上，找出错误的原因并进行针对性的学习和训练。
四、保持积极的心态在解决高三复习阶段的错题过程中，保持积极的心态非常重要。
2020-2021学年高三地理一轮复习易错题01 地球与地图(含答案)
易错点01 地球与地图易错题【01】无法分清大圆和最短航线若两地的经度差不等于180度，则经过这两点大圆不是经线圈，而是与经线圈斜交，其最短航线不经过极点，具体分为两种情况：①甲地位于乙地的东方，从甲到乙最短航程为：同在北半球，先向西北，再向西，最后向西南；同在南半球，先向西南，再向西，最后向西北；位于不同半球时，需要讨论哪一段为劣弧段。
②甲地位于乙地的西方，从甲到乙最短航程为：同在北半球，先向东北，再向东，最后向东南；同在南半球，先向东南，再向东，最后向东北；位于不同半球时，需要讨论哪一段为劣弧段。
易错题【02】无法正确处理等高线和坡度的相互关系根据等高线疏密，判断坡度陡缓。
等高线稀疏的地方表示缓坡，密集的地方表示陡坡，间隔相等的地方表示均匀坡。
等高线的凸出部分指向低处表示山脊，其最大弯曲处的点的连线，表示为山脊线，也叫分水线。
等高线凸出部分指向高处，表示为山谷，其最大弯曲处点的连线，表示为山谷线，也叫集水线。
判断两点间可否通视，可通过绘制地形剖面图判断。
等高线上疏下密表示凸形坡，一般不可视；等高线上密下疏表示凹形坡，一般可视，在等高线图上判断河流流向时，要注意等高线的弯曲方向与河流流向相反。
易错题【03】不会描述地形特征根据等高线判定地貌特征可以从“以何种地形为主”“地势的高低起伏”“各种地形的分布（此条只大范围地区用）”等方面回答。
01无法分清大圆和最短航线西北通道是指从北大西洋经加拿大北极群岛进入北冰洋，再进入太平洋的航道。
以往因冰封影响，航运受限，但未来有望实现通航。
读图，完成下面小题。
1．若不考虑地形等因素，一架飞机从甲地沿最近的线路飞往乙地，则该飞机飞行方向是A．一路正西B．先西北，后西南C．先东北，后东南D．先西南，后西北2．图示区域西北通道的长度约为（cos 70°≈0.342）A．1 800 km B．13 500 km C．5 000 km D．3 330 km【错因】分不清大圆和最短航线，无法确定劣弧【问诊】1．图中甲、乙两地同位于北半球，所以二者之间最近距离应为凸向北极附近的劣弧弧长，所以飞机从甲地到乙地的飞行方向为先向西北再向西南。

查补易混易错03化学用语的判断-2023年高考化学三轮冲刺过关(全国通用)(原卷版)
查补易混易错03 化学用语的判断化学用语是专门的化学语言，其包含的内容可分为两个大的方面：一是表示化学物质组成、结构的化学用语，包括元素符号、离子符号、电子式、结构式、结构示意图等；二是表示物质变化的化学用语，如化学方程式、热化学方程式、离子方程式、电极方程式等。
化学用语类试题比较基础，在复习备考中除了需要注意相关的解题技巧外，还需要对相关知识有比较深入的认识，将知识准确、合理的应用，将相关知识总结归纳，着重关注易错点，并通过练习加强理解掌握，这样才能通过复习切实提高得分率。
易错01常考化学用语S2－：Al3＋：S：······甲烷：乙烯：甲烷：乙烯：易错02电子式的书写1.原子的电子式：将原子的所有最外层电子数在元素符号的周围标出，例如：氢原子()、钠原子()、镁原子()、铝原子()、碳原子()、氮原子()、硫原子()、氩原子()。
2.离子的电子式：（1）阴离子：在书写阴离子的电子式时，须在阴离子符号的周围标出其最外层的8个电子(H－为2个电子)，外加方括号，再在括号外的右上角注明阴离子所带的电荷数，例如S2－的电子式为[]2－，OH－的电子式为。
（2）阳离子：对于简单阳离子，其电子式即为阳离子符号，如钠离子Na＋、镁离子Mg2＋等，对于带正电荷的原子团，书写方法与阴离子类似，区别在于在方括号右上角标上阳离子所带的正电荷数，如NH4＋电子式为。
3.离子化合物的电子式：离子化合物电子式的书写，是将阴阳离子(阳离子在前，阴离子在后)拼在一起，对于不同价态的离子，也按其绝对值，遵照“大值在中间、小值在周边”的原则书写，如CaCl2的电子式应为。
4.共价型单质分子：必须正确地表示出共用电子对数，并满足每个原子的稳定结构，例如：。
5.共价化合物：共价化合物电子式的书写，基本与共价型单质分子相同，一般为正价者在前。
对于不同价态的元素的原子，一般将化合价绝对值大的写在中间，绝对值小的写在周边，例如：。

高三复习阶段如何进行错题的查漏补缺和强化
高三复习阶段如何进行错题的查漏补缺和强化高三是学生们备战高考的重要阶段，错题的查漏补缺以及强化练习是取得好成绩的关键。
本文将探讨高三复习阶段如何有效地进行错题的查漏补缺和强化，帮助学生们高效备考。
一、错题的查漏补缺1. 建立错题记录高三复习错题时，首先建立一份错题记录。
记录下自己做错的题目、题号、错因等信息，并留下解析和答案。
这样可以方便后续的查缺补漏和复习时的回顾。
2. 分析错题原因每做错一道题，都要仔细分析错误的原因。
可能是知识点没掌握好，也可能是题目理解出错或解题方法不当。
逐个找出错误的原因，有针对性地进行纠正和补充学习。
3. 找出易错点通过错题的整理与分析，找出自己的易错点。
这些易错点可能是一类题目，也可能是某个知识点。
弄清楚自己的薄弱环节，有针对性地进行专项练习和查漏补缺，加深对知识点的理解与记忆。
4. 寻找解题规律在查漏补缺过程中，要注意寻找解题规律。
有些题目可能会出现相似的解法或规律，通过总结归纳，可以提高解题的效率，减少错误。
二、强化练习1. 制定复习计划高三阶段，时间紧迫，需要合理安排复习计划。
在每天的计划中，留出时间进行强化练习。
可以根据自己的实际情况，将强化练习列入每天的复习安排中，确保有足够的时间进行深入练习。
2. 针对性选择题目在进行强化练习时，要根据自己的掌握程度和重点难点，有针对性地选择题目。
可以选择高考真题、模拟试题或专门的强化题目进行练习，重点突破自己的薄弱环节。
3. 注重解题方法和思路在强化练习过程中，要注重解题方法和思路。
不仅要找出题目的解决方法，还要注重解题思路的培养。
通过多种角度去思考问题，培养灵活的解题思维，提高解题的准确性和速度。
4. 定期复习和总结在进行强化练习后，要及时进行复习和总结。
回顾练习过程中遇到的难题和解题思路，巩固所学知识，加深对考点的理解。
同时，及时总结其中的失误和不足，避免同类错误的再次发生。
通过以上方法，高三复习阶段的错题查漏补缺和强化练习可以更高效地进行。

2021年高考复习化学考前30天必练小题第03练 化学计量1．（2021·四川成都市·高三三模）设N A 为阿伏伽德罗常数的值，下列说法错误的是A ．34gH 2O 2中含有18N A 个中子B ．1L0.1mol·L -1NH 4Cl 溶液中，阴离子数大于0.1N AC ．标准状况下，22.4LCH 4和C 2H 4的混合气体中含有C —H 键的数目为4N AD ．足量Fe 与1molCl 2完全反应，转移的电子数目为2N A【答案】A【详解】A. 34gH 2O 2为1mol ，H 中无中子，O 中含有8个中子，所以34gH 2O 2含有中子数=1mol ⨯8⨯2=16 mol 即16N A ，故A 错误；B. NH 4+能水解且水解后溶液显酸性，Cl -离子不水解，但水能发生微弱的的电离，所以1L0.1mol·L -1NH 4Cl 溶液中，阴离子数大于0.1N A ，故B 正确；C. 标准状况下，22.4LCH 4和C 2H 4的混合气体为1mol , 因为CH 4和C 2H 4中都含有4个氢原子，所以含有C —H 键的数目为4N A ，故B 正确；D. 根据Cl 2~2Cl -~2e -可知，足量Fe 与1molCl 2完全反应，转移的电子数目为2N A ，故D 正确； 故答案：A 。
2．（2021·云南高三二模）N A 是阿伏加德罗常数的值。
下列有关说法正确的是A ．常温常压下，1.8g 氘羟基(－OD)中含有的中子数为0.9N AB ．标准状况下，11.2L 戊烯中含有双键的数目为0.5N AC ．28gN 2与足量H 2反应，生成NH 3的分子数为2N AD ．常温下，1LpH=2的HCl 溶液中，H +数目为0.2N A【答案】A【详解】A ．常温常压下，1.8g 氘羟基(－OD)中含有的中子数为A A 1.8g 9N 0.9N 18g/mol⨯⨯= ，故A 正确； B ．标准状况下，戊烯是液体，11.2L 戊烯的物质的量不是0.5mol ，故B 错误；C ．28gN 2的物质的量是1mol ，N 2与H 2反应可逆，1molN 2与足量H 2反应，生成NH 3的分子数小于2N A ，故C 错误；D ．常温下， pH=2的HCl 溶液中c(H +)=0.01mol/L ，1LpH=2的HCl 溶液中，H +数目为0.01N A ，故D 错误； 选A 。
