Bitter Genes 吃苦的基因

Learn about the concepts of genetics, and common genetic traits. Students can check whether they have the “bitter gene” by licking phenylthiocarbamide (PTC) taste test paper.

This is a single gene protein on our tongues. PTC can bind to this protein only with the presence of this gene and taste the bitterness on the paper.

認識遺傳學的基礎概念與常見的遺傳特徵。學生通過舔舐苯硫脲（PTC）味覺試紙來測試自己是否帶有「吃苦的基因」。這是我們舌頭上的一種單基因蛋白質。 PTC只有在這種基因存在的情況下，才能與這種蛋白質結合，並嚐到紙上的苦味。
