Nature reserve not only is a nature museum and a gene bank , but also plays a main force to protect the environmental security 自然保护区不仅是一个国家的自然综合体的陈列馆,野生动植物的基因库,而且也是维护环境安全的主力军。
In short , people who were better at imitation thrived , and the genes that gave them the bigger brains required for it consequently spread in the gene pool 简言之，模仿能力强的人会生养众多，使他们拥有大脑子的基因，因此会在基因库中占优势。
But seed orchards are difficult to control , because tree pollen spreads so far that alien , non - elite trees almost inevitably muddy the gene pool 但是有种子的果树很难控制，因为花粉传播的太远了，一些其它种类的树木就会不可避免地弄乱此基因库。
There exist abundant type of animal and vegetation , which are rarely seen in similar kind of areas and enlarge the gene bank of wild biology 物种多样性主要表现为：植被种类繁多，动物类型复杂多样，是同类地区所罕见的，大大丰富了我国野生生物基因库。
In 1989 we created a library of h . pylori genes by inserting selected fragments of the bacterium ' s dna into cells of e . coli 我们在1989年时，将选取的幽门螺旋菌基因片段插入大肠杆菌的dna中，让大肠杆菌制造幽门螺旋菌的蛋白质，以此建立了幽门螺旋菌的基因库。
It is bestowed with rich natural resources , making it a famous homeland of non - ferrous metals , key forest area , production base of bamboo 自然资源丰富，是全国有名的有色金属之乡，中国重点林区，广东毛竹基地。被誉为华南物种基因库和珠江三角洲的生态屏障。
There are worries that those few dozen embryonic stem - cell lines represent too narrow a gene pool , and that they cannot be endlessly extended without damaging them 研究者担心，有限的胚胎干细胞株仅仅代表了基因库里很小的一部分，而且并不能毫无损伤的进行无穷尽的增值。
My thoughts were that a wider based gene pool would provide more possibilities to avoid doubling up on the inherited breed problems i had been regularly experiencing 我的想法是建立在基因库会提供更多的避免使遗传问题加倍的可能性，这些问题是我曾经经历过的，并且是有规律性的。
Two positive clones were obtained and sequenced . using the blast against ncbi gene database , they were comfirmed to be the cdna fragments of testin and actn1 筛选得到两个阳性克隆，测序后经blast软件比较基因库确定这两个阳性克隆中所含cdna分别为已知基因testin和actn1的片段。
