①a、b过程都以DNA为模板，以脱氧核糖核苷酸为原料，都有酶参与反应

②原核细胞中b、c过程同时进行

③人体细胞中，无论在何种情况下都不会发生e、d过程

④在真核细胞有丝分裂间期，a先发生，b、c过程后发生

⑤能特异性识别信使RNA上密码子的分子是tRNA，后者所携带的分子是氨基酸

⑥真核细胞中，a过程只能在细胞核，b过程只发生在细胞质．

运行相应的程序．若输入x的值为1，则输出y的值为（    ）

    What's this? It's letter(字母)P. What colour is it? It's green. What's this and what colour is it? It's letter E. It's brown. What's this letter? It's letter N. It's red. P—E—N. Is it“pen”? Yes, it is.

    I have a blue pen in my pencil case(铅笔盒). My pencil case is orange. This is my book. It's my Chinese book. It's in my bag. My bag is black. Look! The bag is on the chair. The chair is yellow. It's my chair. It's nice. I like it.
