有一种新的方法使研究者在基因工程小鼠中预防腭裂这种出生缺陷.科学家用一种技术来精心地鉴定出胎儿发育的短期内有一种特殊的基因开启了.该技术提供了引起人腭裂以及其他出生缺陷的线索.从一单个受精卵创建出一个复杂的多细胞动物的过程,典型地需要成千上万个基因的协同活性. A new approach has allowed researchers to prevent birth defects in cleaved palates in genetically engineered mice, a technique by which scientists have carefully identified a particular gene that is turned on in the short term of fetal development, Cleft palate and other birth defects The process of creating a complex multicellular animal from a single zygote typically requires synergistic activity of thousands of genes.
