※ 引述《supertony1 (￾NN ￾ ￾ N )》之銘言：
: 6. Bacteriophages that have become integrated into the host cell
:    chromosome are called
:    a.plasmid     b.transposons
:    c.prophages   d.T-even bacteriophages

c是指溫和型ㄉphages(感染初期)
d又是啥...?..晚期ㄉ嗎?

我會比較想選c


: 8.A lomg-day plant will flower if
:   a.the duration of continuous light exceeds a critical length
:   b.the duration of continuous light is less than a critical length
:   c.the duration of continuous darkness exceeds a critical length
:   d.the duration of continuous darkness is less than a critical length

答案d
所謂長日照..即短夜植物....
植物開不開花與夜間長短有關...
與日照時間無關...(就定義來說)
所以小於臨界值即可....

雖然不知道D是啥，但看起來就只是某種phage而不是prophage
反正C一定對嘛

沒錯答案是D而不是A...記得書上把暗期中斷導致長日照植物開花的實驗吧
