以下为本人解法 正确性不知(汗....)
※ 引述《smallmin (小名)》之铭言:
: 1. A hydrophobic portion of a substrate molecule would most likely fit into a
: _____ region of its enzyme's active
: A) positive charge
: B) negative charge
: C) hydrophilic
: D) hydrophobic
: E) polar
一个疏水区会跟疏水区结合 课本相关内容是在流体镶嵌模型那边
模的组成就是外亲水 内两层疏水 还有贯穿模的蛋白 在模内的部份也是疏水
这题是 (D)
: 2. Suppose that gene X,Y and Z are linked and that crossing-over occurs between
: X and Y 20 percent of the time,between Y and Z 30 percent of time,and
: between X and Z 10 percent of time.Which gene are farthest apart on the
: chromosome?
: A) X and Y
: B) X and Z
: C) Y and Z
: D) X and Y,Y and Z (equally far apart)
: E) X and Z,Y and Z (equally far apart)
: ----------------------------
题目要点简述如下: X跟Y距离20% Y跟Z距离30% X跟Z距离10%
如果要画成图就是这样
Y------X---Z
20% 10%
全部(Y-Z)是30%
他问你哪段长?
(A)距离20%
(B)距离10%
(C)距离30%
(D)X-Y跟Y-Z不等长 错误!
(E)同上
所以这题是(C)
ㄜ...错了的话 不要打我><
