问题转基因生物
转基因动植物是遗传工程实验的产物，在这个实验中，一个生物体的基因物质被移入另一生物体，因而受体就能显示出新的特征。商界、科学家和农民都希望转基因的技术能够培育出更多具价格优势、而且是最近的培育技术无法培育的恰遂人愿的动植物。转基因的技术能使遗传物质在两种完全不相干的生物体之间进行转移。为了启用转基因技术，基因工程师必须首先培育一个转基因。在培育转基因时，科学家通常用一个将在受体动物或植物的恰当组织中活动的启动子序列替代原有的启动子序列。总的说来，转基因技术比传统的育种方法具有更多优势。据称，转基因技术育种的目的更精确、速度更快捷、成本更低廉。目前的研究工作仅局限在与一个或数个相关的特征上。科学家们要驾轻就熟地调配动植物复杂的特性，尚需长期的研究。

选项

答案 GMO
Transgenic plants and animals result from genetic engineering experiments in which genetic material is moved from one organism to another ( from organism to organism) , so that the recipient organism (the latter) will have/ show/ display/ exhibit new characteristics/ features. The business circle/ Business corporations, scientists, and farmers hope that transgenic techniques will allow more cost-effective plants and animals (crops and herds) with desirable characteristics that are not available using up-to-date breeding technology. Transgenic techniques allow genetic material to be transferred between completely unrelated organisms. In order for a transgenic technique to work, the genetic engineer must first construct/ develop a transgene. When making a transgene, scientists usually substitute the original promoter sequence with one that will be active in the correct tissues of the recipient plant or animal. Overall/ Generally, the transgenic technology has many advantages over traditional/ conventional methods in many aspects/ areas. Transgenic breeding/ The technology/ It is said to be more specific, faster, and less costly. Right now research is limited to one or a few traits. Before scientists can flexibly regulate/ manipulate complex traits, there is going to be the need for many years of research.
