問題詳情
第二篇：Scientists have discovered dozens of genetic variations that decide how tall we are, which can help us understand whyhumans are so different from one another. The discovery could also lead to new treatments for growth disorders as well asmany other conditions 36 heart disease, cancer and diabetes. Professor Guillaume Lettre, of Montreal University inCanada, said: “Of these 83 genetic variations, some influence adult height 37 more than two centimeters, which isenormous.”Height is mostly determined in our DNA—children from tall parents tend to grow up to be taller, and 38 fromshort parents are shorter. But growth from a small baby into an adult, and the role of genetics, is one of the most poorlyunderstood areas of human biology. According to Professor Lettre, the identified genes will be helpful in 39 aperson’s risk of developing certain growth disorders. There is also the hope that scientists may 40 be able to use thisknowledge to develop a new medicine for growth disorders.

科學家們已經發現了幾十個遺傳變異，決定了我們有多高，這可以幫助我們理解為什麼人類彼此不同。這一發現還可能導致新的生長障礙治療以及許多其他疾病，包括心髒病，癌症和糖尿病。加拿大蒙特利爾大學的Guillaume Lettre教授說：“在這83種遺傳變異中，一些影響成年身高超過兩厘米，這是巨大的。”身高大多是由我們的DNA決定的 - 高個子的父母往往會長大要高一些，矮個子矮一些。但是從小嬰兒到成年人的發育以及遺傳學的作用，是人類生物學中知之甚少的領域之一。根據Lettre教授的說法，被鑑定的基因將有助於預測一個人發展某些生長障礙的風險。也希望科學家有朝一日能夠利用這些知識開發一種新的生長障礙藥物。
