cloning efficiency

The incomplete reprogramming of donor cells was the most important reason for the low efficiency of cloning and developmental abnormalities of cloned animals.

供体细胞的不完全重编程是导致其效率低和发育异常的重要原因。

In order to improve the complex high-dimensional state space search efficiency, and to obtain better tracking results, the parallelism of quantum computing will be introduced to the immune cloning algorithm among is used to solve the three-dimensional human motion tracking problems.

为了提高对复杂的高维状态空间的搜索效率，求得更优的跟踪结果，将量子计算的并行性引入到免疫克隆优化算法之中，用于求解人体三维运动跟踪问题。

It is generally believed that the low efficiency of cloning is due to the incorrect or incomplete nuclear reprogramming of the differentiated somatic cells after nuclear transfer. One of which is the abnormal DNA methylation and histone modifications.

一般认为克隆效率低下与重构胚不正确或者不完全的重组而导致的错误表观修饰相关，其中最主要的就是DNA甲基化异常和组蛋白修饰错误。

Recently studies suggested that, such as DNA methylation and histone acetylation, could affect directly the cloning efficiency and transgene expression during reprogramming process of somatic cells.

已有的研究表明，体细胞重编程过程中，DNA甲基化、组蛋白乙酰化对克隆效率和转基因表达都有直接的影响。

Application of animal cloning is limited with especially low efficiency and birth defect cloned offspring.

目前动物克隆技术的应用因低效和后代生长发育异常等缺陷而受到限制.
