根据文章开头第一句“Identical twins (同卵双胞胎) may not be exact copies at the DNA level after all.(同卵双胞胎在DNA水平上可能并不完全相同。)”这是科研人员的新发现。是文章主题句,后面详细阐述研究过程的详情,与A项内容Some Identical Twins Don't Have the Same DNA(有些同卵双胞胎并不拥有相同的...
Only 38 pairs of twins had all the same genes. Most twin pairs differed somewhat in their DNA. Those differences likely arose long before birth. It could have happened either just before one embryo split to form two or it could have happened shortly after the split. Some of the twins had...
(这两个DNA样本是完全相同的。) - 在描述外观、功能、性质等方面完全一致的物品时也可以使用。 - 例如:“The twins look identical.”(这对双胞胎看起来一模一样。) 2. **Same**: - 适用于各种场合,从正式到非正式都可以使用。 - 可以用于描述人、物、地点、时间等方面的相同性。 - 例如:“I want the...
Do identical twins have the same DNA? Identical twins have almost identical DNA, it was previously thought that the DNA was entirely identical. In 2013, scientists discovered a way to find subtle differences in their DNA which could prove vital in solving crimes and paternity cases that involve...
Classifying identical twins is a challenging problem for some automatic biometric systems. Palmprint has been studied for personal identification for over seven years. Most of the previous research concentrates on algorithm development. In this paper, we systemically examine palmprints from the same DNA...

Not All the Identical Twins Look the Same D. Identical Twins Attract[Many Researchers 相关知识点: 试题来源: 解析 答案见上5.C 推理判断题。 根据第一段可知,同卵双胞胎在DNA水 平上可能并不完全相同。 研究人员在《自然遗传学》杂志上 分享了他们的新发现。 由此可推断,在第一段中,作者直接 给出...
Does identical twins have the same fingerprints? They come from the same fertilized egg and share the same genetic blueprint. To a standard DNA test, they are indistinguishable. But any forensics expert will tell you that there is at least one surefire way to tell them apart:identical twins...
Identical twinshave the same DNA. 同卵 双胞胎的 DNA 完全相同 OpenSubtitles2018.v3 You were anidentical twin. 妳們 是同卵 雙生 OpenSubtitles2018.v3 They soon find out they areidentical twins. 檢查後確認二人為同卵雙胞胎,外观上一模一样。
Identical twins come about when a single fertilised egg splits in two, meaning they haveexactly the same DNA– theyare clones. Fraternal twins form when two separate eggs are fertilised by two separate sperm. Because each egg and sperm has a differentmix of parental DNA, only 50 per cent ...
