第七套滚动内容十细胞的生命历程(B卷)1.A【解析】细胞周期包括分裂间期和分裂期,分裂间期结束后开始进行有丝分裂,A项正确;细胞周期的大部分时间处于分裂间期,占细胞周期的90%~95%,B项错误;连续分裂的细胞才具有细胞周期,生物体中不进行连续分裂的细胞不处于细胞周期中,C项错误;有丝分裂前期,染色质高度螺旋化形成染色体,D项错误。2.A【解析】本题考查有丝分裂过程中染色体的变化。双定向作用能保证着丝粒分裂后产生的子染色体分别向两极移动,从而实现染色体平均分配,A项正确;染色体数目的加倍是着丝粒分裂导致的,与双定向作用不存在因果关系,B项错误;双定向作用是进行分裂的细胞中存在的现象,而根尖成熟细胞不具有分裂能力,因此不是所有细胞都存在双定向作用,C项错误;“若该作用出现异常,便暂停有丝分裂的继续进行。”据此可推知限制有丝分裂的双定向作用会影响细胞周期的完整性,D项错误。3.B【解析】细胞群体甲所有细胞均被3H-TdR标记,细胞群体乙多次分裂后细胞不一定均含有3H-TdR标记,A项错误;S期进行了DNA的复制,G2期有RNA和蛋白质合成,为纺锤丝形成做准备工作,故最先进人M期的标记细胞是S期最晚期细胞,B项正确;S期进行了DNA的复制,培养液中缺乏脱氧核苷酸供应,细胞停留在S期,C项错误;培养液中加入秋水仙素,抑制了纺锤体的形成,M期细胞比例增加,D项错误。4.D【解析】自由基的来源主要有细胞内的氧化反应、辐射以及有害物质,最为严重的是,当自由基通过②攻击生物膜的组成成分磷脂分子时,过程①的产物同样是自由基,这种反应为正反馈调节,A项错误;若③过程使酪氨酸酶活性降低,将引起头发变白,白化病是由基因突变,酪氨酸酶缺乏引起的,B项错误;若③过程使细胞膜上葡萄糖的载体受损,葡萄糖将无法进出细胞,C项错误;④过程将导致基因突变,可能引起细胞癌变,癌变细胞膜的成分发生改变,有的产生甲胎蛋白、癌胚抗原等物质,细胞膜上的糖蛋白等物质会减少,D项正确。5.D【解析】由题意知,ASURA的化学本质为蛋白质,因此其合成场所为核糖体,合·25【23·G3AB(新高考)·生物学·参考答案一R一必考一TJ】
