您要查找的是不是:
- 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 pairing 互补碱基配对
- complementary base pair 互补碱基对
- It base pairs with adenine in the complementary strand of DNA. 在互补DNA中的配对碱基为腺嘌呤。
- There are three million base pairs in human DNA. 人类基因组中有30亿个基对。
- 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。
- 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 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。
- 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。
- 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。
- 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。
- Base pairing The bonding relationship between purine and pyrimidine bases in the nucleotides of DNA and RNA. 碱基配对:在DNA和RNA的核苷酸中,嘌呤和嘧啶之间相匹配的关系。
- 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。
- 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。
- 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。
- 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。
- He invented a technique to determine the sequence of base pairs in dna. 他发明了一种技术来测定DNA的碱基对序列。
