想藉這個標題請教一題 20.A singal sequence has to be expected in the precursors of all the following proteins except A.ribosomal proteins B.the sodium-potassium ATPase in the plasma membrane C.collagen in the extracellular matrix of connective tissue D.signal peptidase E.acid maltase, a lysomal hrdrolase 這題我是選A 印象中singal sequence似乎是可以把合成出來的蛋白帶去他該去的地方... 有人知道這一題該選誰嗎?? 40.Interferon activated enzyme A.phosphatase B.phosphorylase C.phosphodiesterase D.Janus kinase E.Akt/PKB 這一題我就不知道要怎麼選了= = 請高手幫幫忙~謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.174.206.175
