試題評析
曾正老師試題評析
一、各類命題最高之幾個部分:
1.演化、生態學:17 題。
2.分子生物學:15 題。
3.遺傳工程:4 題。
4.發生遺傳學:5 題。
其他零星命題:1~3 題。
二、超過生物教本題目,一共出現了 7 題,生物題庫班即講授了 4 題。
三、上課講義、練習卷、考前猜題,第三次模考皆有命中。
四、如往常,考前有人散佈不考 Campbell 生物教本,事實證明,試題大部分可由 Campbell
找到芳踪。
五、本班優秀同學可拿到 80 分以上;中等程度亦有 70 分。
六、往後建議:
1.對修習過分子生物學、生化同學有利。
2.上題庫班多學課外補充。
3.死背口訣,不必弄懂的學習方式,勢必淘汰。
4.一定要理解,自然可記憶。
七、爭議試題:
1.第 31 題有誤:MPF 在 M 期到達高峰,選項(B)錯誤,答案應改為(B)。
可參考 Campbell (7E) p.230。
2.第 66 題有誤:
(A) genomic library 不需運用 reverse transcriptase.
(B) genomic library 含有 intron sequences
故選項(A) (B)皆錯。
可參考c Genetics by Brooker 3E(2009)—偉明出版 (P.497)
d Principles of Genetics by Simmons 4E (2006)
—偉明出版 (P.430~431)

楊老師試題評析
一、此份試題比去年難,除了以 campbell 為出題藍本之外,另外還有許多其它書本的題目。
二、許多觀念講義雖有提到,但是經題目的一番變化,若只有死背答案則會吃大虧。
三、仍有考古題,及與講義完全相同的題目:如第 7 題、第 47 題、第 5 題…
四、遺傳考 4 題,分生 22 題,佔 33%,比去年多(去年 21%)(前年 30%)
五、動物生理考 13 題,佔 18%,比去年少(去年 30%)(前年 2 6%)
六、分類、演化考 12 題,佔 20%,比去年多(去年 4%)
七、植物學考 4 題,佔 6%,比去年少(去年 10%)
八、生態學考 9 題,佔 11%,比去年多(去年 4%)
九、能量學去年幾乎沒有考,今年考 3 題,佔 3%
十、其它如細胞生化及基本概論佔 10%
十一、整體而言,題目比去年平均但在寫的過程中,會覺得分生題目很多,其原因是因
為分生出的比較難(正規課本上面並非都有寫)
,如第 28、30 題,32 題也出的很細
節(當然講義上還是有)
十二、有部分題目雖然生物學有提及但所提的內容未深入,因此看起來題目似乎簡單,
但是下筆卻又很困難,如第 58 題、第 62 題及第 74 題。
十三、許多題目是綜合性的應用題,所以題目算是很活。
十四、爭議試題有二:
1.試題一:
(C)31.
MPF is a cyclin-Cdk complex that was discovered first in Xenopus egg. Its activity
fluctuates
during cell cycle.
Which of the following is NOT its characteristic?
(A) Fluctuationof the cyclin concentration is the same as MPF activity.
(B) The peak of the MPF activity is G2 phase.
(C) The peak
of the MPF activity is M phase.
(D) The breakdown of the MPF occurs abruptly
during M phase.
(E) The activity of the MPF promotes mitosis by phosphorylating various proteins.
根據
Campbell 7
th
第 230 頁
Figure 12.16 Molecular control of the cell cycle at the G
2
checkpoint. The steps of the
cell cycle
are timed by rhythmic fluctuations in the activity of cyclin–dependent kinases
(Cdks). Here we focus on a cyclin–Cdk complex called MPF, which acts at the G
2
checkpoint as a go–ahead signal, triggering the events of mitosis.

可由上圖看出:
cMPF 在 M 期突然被崩解2MPF 的活性波峰也是在 M 期,故(D)及(C)選項
都是正確的,此題是選錯誤的,故此題無解。
2.試題二:
(E) 66.
Which one FALSELY describes a genomic library?
(A) A genomic library must be performed
with a restriction enzyme, a DNA ligase,
and a reverse transcriptase.
(B) A genomic library contains only coding sequences.
(C) Plasmids can be used the cloning vector for making genomic libraries.
(D) A genomic library is a "shotgun" approach-no single gene is targeted for cloning.
(E) None of the above.
根據 Campbell 7th 第 389 頁
Figure 20.6 Genomic libraries. A genomic library is a collection of many bacterial or
phage clones, each containing copies of a particular DNA segment from a foreign
genome. In a complete genomic library, the foreign DNA segments cover the entire
genome of an organism. (a) Shown are three of the thousands of “books" in a
plasmid library. Each “book" is a clone of bacterial cells, each containing copies
of a particular foreign genome fragment (pink, yellow, black segments) in its
recombinant plasmid. (b) The same three foreign genome segments are shown in three
“books" of a phage library.

由上敘述可知
1genomic library 是有可能含 intron(符合 B 選項的應該是 cDNA)
2genomic library 不需經反轉錄(符合 A 選項的應該是 cDNA)
故此題答案應該是(A)和(B)
