opsin n.【生物化學】視蛋白。

opsonic

Researchers can figure out the evolutionary relations of opsins in the various classes of cones and from different species by examining the sequences of nucleotide bases ( or dna “ letters ” ) in the genes that code for these proteins 透過比對視蛋白基因的核苷酸鹼基(或稱dna字母)序列,研究人員就能找出不同錐細胞視蛋白以及不同物種間視蛋白的演化關系。

The resulting evolutionary trees reveal that opsins are ancient proteins that existed before the emergence of the predominant groups of animals that populate the earth today 研究出來的演化樹顯示,視蛋白是種古老的蛋白質,早在現今居住地球上的優勢動物類群出現之前就已經存在了。

The opsins that distinguish one cone from another have provided a way to study the evolution of color vision 可用以辨別不同錐細胞的視蛋白,讓我們找到了研究色覺演化的方法。
