A man whose last name was Sun is in the hot seat for stealing a woman’s seat on a high-speed train on Aug 21, 2018. In a video posted on Sina Weibo, the man can be seen sitting in a seat. When the woman asked him to give her seat back, he refused and said that she had three choices– stand, take his seat or go to the dining car. A train attendant then tried to ask him to give the seat back. Sun said that he wasn’t able to stand on his own and asked for a wheelchair. Left with no other choices, the attendant led the woman to another seat, China Daily reported.The video quickly spread onlin碱基互补配对可发生在下列哪些生理过程或生物技术中 ① 种子的萌发 ② 病毒的增殖 ③ 细菌的分裂 ④ 目的基因与运载体的结合 ⑤ DNA 探针的使用 ⑥ 分泌蛋白的加工和运输 A ． ①②③④⑤  B ． ①②③④⑤⑥ C ． ②④⑤   D ． ②③⑤⑥
