Genes are specific sequences of bases that encode instructions on how to make proteins 基因是一種含編譯蛋白質(zhì)制造命令的特殊堿基序列。
This binding capability can be pinpointed to a characteristic base sequence known as a homeobox 這種能力與被稱為同源框的特定堿基序列有關(guān)。
Based on the results of rflp there are clear differences between species in both genera metarhizium and paecilomyces 蟲草屬rdnaits堿基序列分析結(jié)果表明:以子囊殼埋生和子囊殼非埋生或半埋生將蟲草分成兩類。
More than one person might have a particular rflp pattern , but it becomes less likely that multiple people will have two or more base sequences in common 具有一個(gè)獨(dú)特rflp圖案的人可能不只一個(gè),但是多數(shù)人共同具有兩個(gè)或更多的堿基序列幾乎是不可能的。
With the increasing of knowledge about human beings diseases it is found that the mutations of base sequence in dna are responsible for numerous inherited human disorders 脫氧核糖核酸( dna )被稱為生命體內(nèi)的遺傳物質(zhì),研究發(fā)現(xiàn)人類的許多遺傳疾病都與dna分子中堿基序列的變異有關(guān)。
Gene duplication is one of the most important factors that influence the evolution of genome size , the origination of novel gene , the genetic robustness against null mutations , the speciation , etc 摘要基因重復(fù)是基因通過不等交換、逆轉(zhuǎn)錄轉(zhuǎn)座或全基因組重復(fù)等途徑產(chǎn)生一個(gè)與原基因相似的基因或堿基序列。
Escherichia coli promoter , which could initiate transcription of a gene , was mainly consisted of two conserved sequences , - 10 box and - 35 box , and spacer between them , whose length is changeable 大腸桿菌啟動(dòng)子能起始基因的轉(zhuǎn)錄,它主要由兩段比較保守的序列片斷- 10框、 - 35框和它們之間一段長(zhǎng)度可變的堿基序列組成。
If scientists could recreate his genome , the strings of billions of letters that spell out how to build and run a neanderthal , they would be able to pinpoint the precise difference between the two species 如果科學(xué)家可以重構(gòu)其基因組,一串可以拼出如何構(gòu)建和運(yùn)轉(zhuǎn)一個(gè)尼安德特人的數(shù)十億堿基序列,那么他們將可以查明這兩個(gè)物種之間的精確差異。
Considering the essential doctrine of designing pcr primers , two regions in which all tigers share an unique hyplotype against other species were selected to design a pair of primers ( primer 1 , 2 ) to amplify a tiger cytb fragment specifically 發(fā)現(xiàn)在361 - 381位點(diǎn)之間和565 - 585位點(diǎn)之間,虎的dna堿基序列與其他貓科動(dòng)物、鹿科動(dòng)物有多個(gè)位點(diǎn)不同。
