克隆 作文

cloning
都填ing
in是介词,后面加动词现在分词

正确的 植物组织培养最终产物是个体植株 细胞培养最终产物仍旧是细胞

Clone,to a certain degree,is beneficial to mankind.Such disease as Parkinsons will possiblly be cured in the future in the hope of further applying of clone.However,the abuse of this technology will bring human being unthinkable destruction.
But cloning still has some problems.The scientists found that the cloning animal’s Gene has a little different from the original animal.So the life will shorter than the real life.The fact proved that,the cloning sheep Dolly has died.It only has the half life of the common sheep.

克隆快乐阅读答案

您好!
有趣的问题,照地球的环境改造别的星球,例如火星,是可能造出类地星球的.可是不可能完全一样.
克隆（clone）是指通过无性生殖而产生的遗传上均一的生物群,即具有完全相同的遗传组成的一群细胞或者生物的个体.克隆在希腊语中是“小树枝叶”的意思,用以指无性增殖物.现在则指个体、细胞、基因等不同水平上的无性增殖物.（1）个体水平：在植物的无性增殖中,植物的发芽、插条等由同一个体通过无性生殖而增长的个体群均被视为克隆.采用组织培养方法可使植物细胞培养发育成完全的个体（愈伤组织）,采用这种方法得到的具有相同基因型的个体群,也被称为克隆；在动物的无性增殖中,典型的例子是采用核移植实验方法,把分化细胞的核移植到一个事先去核的蛙卵中,让其发育并得到克隆蛙.克隆动物具有均一遗传性质,在研究环境条件对发育、分化的影响以及药物的检测方面都是重要的实验材料.在哺乳动物中,由于细胞分化,核异质化的程度加剧,因此核移植尚无成功的例子.（2）细胞水平：由一个细胞经过有丝分裂生成的细胞群叫克隆.但如果培养细胞发生转化,则很容易引起染色体变异.（3）基因水平：利用基因重组操作技术,使特定的基因与载体结合,在细菌等宿主中进行增殖,有可能得到均匀的基因群.克隆基因在基因功能与精细结构的关系等基础研究及在有用物质的生产方面,均已得到应用.
在上述3种水平上,增殖并分离获得单一的克隆群称为克隆化.此时,克隆一词也可作为动词理解.克隆是重组DNA技术的核心部分.事实上,克隆技术现已被人们用来通过营养方式繁殖病毒等微生物和植物的纯种,从而保证了这些生物基因组的准确连续性.现在,克隆这个词还包括单个自主遗传因子的分离与保存.细胞生物的克隆只需要营养培养基,而基因的克隆则需要某种载体复制子、特定的寄主细胞和营养培养基.各种类型生物的克隆技术在生物工程中均有其重要作用.

科学上讲,所有细胞都具有全能性,就是说所有生物均可克隆,只是克隆的难易程度有所不同,像植物就比动物容易克隆.人类克隆早已成功,只是目前已禁止!动物克隆的成功率也逐渐上升,克隆牛技术已经成熟!

My View on Clone
With the repid development of technology, clone comes to the world. It can duplicate creature, which means it
can make contribution to the production. People can pay a little and get a lot in the end. However, it also
has disavantages. I think as the development of the high-tech, people can use clone to copy humen beings. It’
s so horrible for me to know that there is someone the same with me. But in general, clone has more advantages
than disadvantages.
