※ 引述《ISME0907 (ISME)》之銘言:
: 1.The role of testosterone in male reproductive function include all of the
: following EXCEPT
: 這題答案給 stimulating spermatogenesis by Leydig cells
: 我覺得有點問題,因為 LH -> Leydig cell -> testosterone -> Sertoli -> 精子生成
: 大家因該有學過此機制吧~
spermatogenesis是Sertoli直接造成
: 2. What features of meiosis allow for independent assortment of chromosome?
: A.random alignment of homologous sister chromatids on the metaphase plate.
: B.separation of sister chromatids
: C.reduction of chromosome number from diploid to haploid
: D. B+C
: E. A+B+C
: 此題答案為A~
: 題目要問的是獨立分配律是何者?給A我覺得好像對又不對,因為獨立分配律不就是
: 在減數分裂I時,同源染色體分開,非同源染色體可任意組合到個子細胞中~;而A選項
: 中random alignment of homologous sister chromatids已經講到減數分裂II去了,
: 請問是我對獨立分配律的見解有問題嗎?
random alignment of homologous sister chromatids指的是同源染色體排在一起
是減數分裂I 不是減數分裂II
: 3. Which of the following is not a way that bacteria benefit human?
: A.produce foodstuffs such as cheese
: B.produce antibodies
: C.break down substance harmful to human, such as waste, toxin, explosives
: and petrochemicals
: D.kill harmful insect
: E.transfer nutrient across instinal membrance.
: 這題答案為E,但沈老大他說要把答案給為C,我覺得老師錯了,因為在題庫的下一題
: 就有說C選項是一種生物調節,如此看來對人類當然有利~大家怎麼看呀~
E我不知道 但C絕對是對的
: 以下是是非題
: 4.In terms of cell signaling estrogen in animal cells works in a similar
: fashion as the plant hormone auxin via binding to intrecellular receptor.
: 答案是TURE~
: 我認為答案錯了~auxin的受體是在膜上吧~
似乎都有
: 5.Maternal effect genes are inherited via the mitochondria.
: 答案是FALSE~
: 我認為母效基因的確可在粒線體,所以一些粒線體引起的疾病大多是因母親方面所提供的
: 卵裡有錯誤的DNA,大家覺得呢?
: 大家加油囉~
: 希望這些問題可以出現在考題上,大家看到賺到^^~
Maternal effect gene指的是未受精卵內的決定因子
和粒線體不相干
