The initial step in developing a biotechnological process is generally a search for a suitable organism.Such organisms will be exoected to create a product or service that will generate a financialreturn to that industry .In practice,the geneticist has to select an organism that produces the desired product.Once a suitable organism is foumd ,conventional breeding and mutagenesis methods are used where possible to induce genetic changes that may produce even more of the desired product .Selection of imoroved organisms is tedious and time demanding and most of the methods available to the geneticists up until recently have involved trial and error .However ,new genetic technologies ,i.e.protoplast fusion and the use of recombinant DNA techniques ,are allowing new approaches by which useful genetic traits can be inserted directly into the chosen organism .Thus ,totally new capabilities can be engineered and microorganisms in particular and plant and animal cells to a lesser extent may be made to produce substances beuond their naturally endowed genetic capabilities.
开发生物技术进程的第一步通常是寻找一个合适的有机体.这个有机体期望能够创造一种在行业内产生利润回报的产品或服务.在实践中,遗传学家要选择一个能生产预期产品的有机体.一旦找到合适的有机体,在常规育种和诱变方法的基础上引入基因变异,甚至可能会产生更理想的产品.改良有机体的选择是一个单调而耗费时间的过程,而且大部分能被遗传学家们使用的方法直至今日也只是在通过反复试验,从失败中找到的方法.然而,新的基因技术(例如原生质体融合和DNA重组技术)可以使用新的方法直接将有用的遗传特征植入到所选择的有机体中.因此,可以设计出全新的功能,特别是对微生物和动植物细胞,在一定范围内可以赋予其超出其自然本能的遗传特征.
