When they were young, Jeffrey and Brett Whitworth used to impersonate each other around school. As identical twins, they found it easy to confuse people.But an appellate court has rejected the implication that that's behind a bizarre child-support dispute in Illinois, one that has pitted the ...
Identical twins (同卵双胞胎) may not be exact copies at the DNA level after all. Normally, identical twins differ by 5. 2 genetic changes. Researchers shared their new finding in Nature Genetics.Identical twins are also called monozygotic twins (单卵双胞胎). They come from a single egg. ...
根据原文最后一段“Researchers in Iceland studied 381 pairs of identical twins. Then the scientists studied all the genes in each person carefully. Only 38 pairs of twins had all the same genes. 冰岛的研究人员研究了381对同卵双胞胎。然后科学家们仔细研究了每个人的所有基因。只有38对双胞胎拥有相同...
Each of these em-bryos will go on to become a baby.Identical twins have long been thought to have the exact same genes. That's why some scientific studies study these twins. Such studies try to determine whether particular features,diseases or conditions are due to genes or instead reflect ...
Identical twins are the same sex and will look the same because they have the same DNA, except for epigenetic changes, but of course external factors such as haircuts, clothes and weight can make identical twins physically distinguishable from each other. ...

DNA分子是由2条逆平行的多核苷酸长链围绕着一个中心轴盘旋转形成螺旋状结构，2 条多核苷酸链上的碱基严格按照互补（C—G、A—T）规律结合成对，结合后的2个碱基成碱基对。在DNA 分子中碱基的排列顺序决定了某段DNA特性，代表了某种遗传信息，DNA大分子的一个片断就是控制生物遗传的基因。在人的1～...
