- 1染色體
A chromosome is a tiny thread inside every living cell. On that thread sit the genes — the instructions that help decide a plant’s or animal’s size, shape, and many other traits. Humans have chromosomes in pairs; you get one set from each parent. You cannot see them with your eyes. Scientists stain them so they show up under a microscope — and that staining is why the name has “colour” in its roots. It is a school-biology word, used in the same way by doctors and by textbooks. People sometimes say “it’s in your chromosomes” to mean “you were born that way”; that is a loose, everyday stretch of a precise science word.
From the word’s history
From German Chromosom, from Ancient Greek khrôma 'colour' + sôma 'body', because they take stain.
借自德文 Chromosom，由希臘文「顏色」加「身體」組成，因為會被染色。
組成From German Chromosom, from Ancient Greek khrôma (“colour”) + sôma (“body”), because they show colour when stained. In English: chromo- + -some (“body”).
