查询词典 gene base

The White Bellied Gene – this gene is something that shows differently on Agouti hamsters (those with cheek flashes/crescents and base colours) and Self hamsters (hamsters that are all one colour without different coloured cheek flashes etc.) Butterbean is a self coloured hamster, Vala is an Agouti hamster, just so that you can see the difference.

The comparison of the genes with white-tailed deer and red deer PrP gene revealed there are five base substitutions produced amino acid mutation, e.g.

与同科不同亚科的马鹿和白尾鹿以及不同科的奶牛和绵羊朊蛋白基因序列比较，核苷酸序列和推导氨基酸序列同源性为97.3%～98.2%和97.7%～98.8%，说明朊蛋白基因在同科和不同科的反刍动物间是保守的。

Part IIMorpholino-mediated translational inhibition and overexpression oftbx2 in zebrafish cardiogenesis Objective To elucidate the role of tbx2 in zebrafish cardiogenesis via morpholino-mediated translational inhibition and overexpression on the base of expression pattern of tbx2. Methods Gene-specific antisense morpholino oligonucleotides were designed to against ATG region of zebrafish tbx2 to knockdown endogenous tbx2 gene.

设计tbx2-MO和对照MO，在斑马鱼受精卵的单细胞期，进行不同浓度的显微注射，并通过荧光蛋白融合标记实验和tbx2-mRNA、tbx2-MO共注射拯救实验，验证tbx2-MO抑制tbx2基因表达的有效性和特异性；基因过表达是通过给斑马鱼受精卵注射体外合成的tbx2-mRNA，来研究tbx2基因功能获得对斑马鱼胚胎心脏发育的影响。

Since Watson and Crick have brought forward the model of DNA helix structure and explain about it's reproduce mechanism in molecule level, research work concerning DNA has been continuously lucubrated. However, whether translating inheritance information and rebuilding DNA molecule via menstruating DNA sequence, or to date the most compelling gene project, chromosome protract et. al, there all need a sort of molecule scissors cleaving DNA, DNA cleavage reagent. At present, tool enzyme of cleaving DNA is mostly DNA restriction enzymes founded in 70 years, which only cleave DNA at specific 4-8 base pair sequences that are usually palindromic, so this restricts the at very fast speed developing of gene technology at certain extent.

自从Watson和Crick提出DNA的双螺旋结构并对其复制机制在分子水平上进行解释后，使得对DNA的研究不断深入，但无论是通过测定DNA的序列来破译遗传信息、改造DNA分子，还是目前最令人关注的基因工程、染色体绘制等，都需要一种断裂DNA分子的&剪刀&——DNA断裂试剂，目前断裂DNA的工具酶主要是上个世纪70年代发现的DNA限制性内切酶，但所知的Ⅱ型限制性内切酶的DNA序列识别长度较短（约为4～8个碱基对），而且一般要求回文结构，这就给飞速发展的基因工程技术带来一定的限制。

A deletionof T base pair was detected at 7bp in intron 1 of sheep TNNC2 gene,which was named allele D.The frequency of allele D deleted was 0.78,0.77 and 0.71 in Small-tailed Han sheep,Tan sheep and Inner Mongolia sheep,respectively,and thedistribution of gene and genotype were no significant difference among the three sheeppopulations by X~2 test(p＞0.05).The association analysis between the genotypes and meatquality traits indicated the genotypes significantly influenced sheep meat quality.
