研究人员向肿瘤细胞中导入单纯疱疹病毒胸苷激酶基因(HSV-TK),可将

研究人员向肿瘤细胞中导入单纯疱疹病毒胸苷激酶基因(HSV-TK),可将某种无毒性前体药物磷酸化,引起肿瘤细胞内一系列代谢变化,最终诱导肿瘤细胞的自杀。相关分析错误的是

A. 该治疗方法属于基因治疗,HSV-TK能遗传给后代

B. 在将HSV-TK导入肿瘤细胞前,需要构建基因表达载体

C. 肿瘤细胞因导入HSV-TK发生的自杀属于细胞凋亡

D. 肿瘤细胞具有无限增殖和糖蛋白减少易扩散转移等特征

答案

A

【解析】A. 该治疗方法属于基因治疗,也属于可遗传的变异,但是HSV-TK能诱导肿瘤细胞死亡,故不能遗传给后代,A错;B. 在将HSV-TK导入肿瘤细胞前,需要构建基因表达载体,保证基因在肿瘤细胞中存活,B正确;C. 肿瘤细胞因导入HSV-TK发生的自杀属于细胞凋亡,属于基因控制的编程性死亡,C正确;D. 肿瘤细胞具有无限增殖和糖蛋白减少易扩散转移等特征,D正确。故选A符合题意。
