3-1 第五段

A chromosome is a single DNA molecule, together with a number of proteins. Each chromosome typically contains thousands of genes.Genetic information coded in your chromosomal DNA is what makes you different from an oak leaf, an alligator,or a flea,and from your parents. This genetic information makes you a member of the human species but also allows you to be a unique member of that species. The relationships among genetic material and cells are depicted in figure 3-2.




染色體是一個唯一脫氧核糖核酸分子，與一定數量的蛋白質一起。 每個染色體典型地包含數以萬計的基因。在您的染色體脫氧核糖核酸編碼的基因信息是什麼使您與橡木葉子不同，鱷魚或者跳蚤和從您的父母。 這基因信息做您成為人的種類，而且允許您是那個一名獨特的成員種類。 在基因和細胞之中的關係在表3-2被描述。
