個重複單位好短 喺下面 ， 呢個就係同一隻蜘蛛嘅 卵鞘或者小管狀絲蛋白嘅重複序列 你可以見到呢啲絲蛋白有幾唔同 所以 ， 呢個就係 蜘蛛絲基因家族多元化嘅美 重複單位唔單止每個長度不一
The repeat unit is very short, and this is the repeat sequence of the egg sheath or small tubular silk protein of the same spider, and you can see how different these silk proteins are, so this is the diversified beauty of the spider silk gene family, and the repeat unit is not only different in length
