- Strictly, a base pair is a pair of complementary bases (i.e. the A:T, G:C and A:U interactions) held together by hydrogen bonds. 严格地说,碱基对是一对相互匹配的碱基(即A:T,G:C,A:U相互作用)被氢键连接起来。
- Complementary base pairing rules 碱基对互补原则
- complementary base pair 互补碱基对

- complementary base pairing 互补碱基配对
- In February, the two groups charting the human genome published their results--the entire 3 billion base pair sequence. 在(2001年)2月份,两个研究小组发表了他们的人类基因组图,也就是30亿碱基对序列结果。
- The base pair ratio, AT:GC, is constant within a species but differs between species. AT:GC之间的碱基比具有种内特异性,但在不同种之间往往是不同的。
- There are three million base pairs in human DNA. 人类基因组中有30亿个基对。
- Sequencing DNA has come down in price by half annually, from $10 per base pair in 1990 to under a penny today. 资讯科技通常不要一年,价格表现比和产能就会增加一倍。
- It occurs in combined form in nucleic acids and several coenzymes. In DNA its complementary Base is guanine. It or its corresponding nucleoside or nucleotide may be prepared from DNA by selective techniques of hydrolysis. 在核酸和几种辅中以结合的形式出现。在去氧核糖核酸(DNA)中,其互补基是鸟嘌呤。借着水解的挑选技术,可从去氧核糖核酸制备胞嘧啶或相关的核或核酸。
- The binding of a series of square planar Pt(II) adducts on the Watson-Crick base pair AT and GC wasinvestigated using advanced quantum chemical method. 用量子化学方法研究一系列Pt(II)配合物作用于嘌呤碱基N7位点后对Watson-Crick碱基对AT、GC的影响.
- Ames test showed that both of the base pair transversion and frameshift mutant in DNA was not induced by irradiated starch. Ames试验也说明辐照淀粉不诱发DNA中碱基对的置换型和移码型突变。
- CONCLUSION: Base pair substitution mutation and frame shift mutation were caused by folpet in Ames test.And DNA breakage in human PMNC might be induced by folpet. 结论: 灭菌丹可引起鼠伤寒沙门氏菌碱基置换和移码突变,并可能损伤人外周血淋巴细胞DNA的完整性。
- For example, achondroplasia, a common form of dwarfism, usually occurs as a result of a mutation at base pair 1138 in a gene called FGFR3 on the short arm of human chromosome 4. 举例来说,软骨发育不全症(achondroplasia,一种常见的侏儒症)通常是人类第四对染色体短臂上FGFR3这个基因的第1138个碱基对发生突变。
- Conventional sequencers evaluate about 1,000 base pairs at a time. 传统定序仪一次约只能评估1000个碱基对。
- It can greatly promote carcinogenesis.DNA diluted alkali firer proves N-nitroso compounds induce the crosslinking between complementary DNA base pairs and initiate cell cancerization. DNA城稀释过滤法证明,N-亚硝基化合物含氮杂环化借诱发DNA互补碱对之间的交联而启动细胞的癌变。
- That DNA bases attract is not a surprise,because base pairs are complementary like right-and left-handed gloves: adenine binds with thymine, cytosine with guanine. DNA碱基对有吸引力并不令人吃惊,因为碱基对就像左和右手套一样是互补的:腺嘌呤约束胸腺嘧啶,胞嘧啶约束应鸟嘌呤。
- How long would it take for the E. coli RNA polymerase to synthesize the primary transcript for the E. coli genes encoding the enzymes for lactose metabolism (the 5,300 base pair lac operon)? 一般认为大肠杆菌RNA聚合酶合成大肠杆菌编码乳糖代谢酶(5300bp的乳糖操纵子)的基因的第一次转录要多长时间?
- Electrochemical detection of DNA hybridization usually involves monitoringof a current response, resulting from the Watson-Crick base pair recognition event, under controlled potential conditions. 将电化学活性良好的纳米金、银以及壳一核型合金纳米微粒,分别标记在疏基修饰的寡聚核昔酸片段上,制备成金属纳米微粒标记DNA电化学探针,通过与固定在电极表面的互补靶DNA杂交后,检测探针上标记物的电化学信号来识别和测定靶序列。
- The human genome contains approximately three billion chemical base pairs. 人类基因组包含大约三十亿个化学碱基对。
