Multiple Choice
下列有關真核生物DNA複製與轉錄作用的敘述，何者正確？
皆以DNA的雙股為模版
使用不同的核苷酸為原料
皆以DNA聚合酶為催化劑
皆以RNA聚合酶為催化劑
31
Multiple Select
RNA分子中含有下列哪些鹼基？（應選項）
胸腺嘧啶T
胞嘧啶C
尿嘧啶U
腺嘌呤A
鳥糞嘌呤G
32
Multiple Select
比較人體中的DNA及RNA，哪些正確？（應選2項）
兩者均呈雙螺旋狀
DNA的分子量大於RNA
兩者所含之嘧啶和嘌呤的數量相等
DNA只出現在細胞核中，RNA只出現在細胞質中
分子生物學的中心法則：DNA→RNA→蛋白質
33
Multiple Choice
關於真核生物進行基因表現的相關敘述，下列敘述何者正確？
DNA上的許多基因皆透過相同的核苷酸序列來攜帶遺傳訊息
一條DNA上的眾多基因皆有著相似的長度
基因的轉錄不全然只發生在細胞核
基因表現依序經過轉譯和轉錄的過程
34
Multiple Choice
當DNA經轉錄作用形成RNA時，原DNA上之含氮鹼基若為A，RNA上與A對應之核苷酸為何？
T，因為嘌呤和嘧啶配對
U，因為RNA沒有T
A，因為RNA沒有T
U，因為轉錄作用為嘌呤和嘌呤配對
35
Multiple Select
附表比較真核生物的複製、轉錄及轉譯作用：模版（DNA或RNA）、發生部位（細胞核或細胞質）、產物（DNA、RNA或蛋白質）。請問下列敘述中哪些正確？（應選3項）
甲為DNA，乙為RNA
丙發生在細胞質
丁發生在細胞質
戊為DNA
己為蛋白質
