Which of the following statements is true?
Traits showing non-Mendelian extranuclear inheritance are always inherited from the mother.
The molecules used to carry out photosynthesis are encoded in nuclear DNA and mitochondrial DNA.
cpDNA is found in the chloroplasts.
Molecular evidence suggests that DNA sequences may have been transferred between mtDNA and nuclear DNA.
Variegated four o'clock leaves have white patches among the green areas due to a mtDNA mutation that blocks electron transport.
五个选项,单选

1.性状表明,非孟德尔的核外遗传来自于母体.
不确切,对于核内的不是,但对于胞质就是,由于卵子比精子大很多,所以对于mtDNA来说,基本还是母体遗传的多,但并不是说父体就不给予.
2.用于进行光合作用的分子均由核DNA和mtDNA编码.
错误,是核DNA和cpDNA编码.
3.cpDNA发现于叶绿体中.
对,cpDNA就是叶绿体DNA.
4.分子证据提示DNA序列在核DNA和mtDNA之间可能有过转移.
个人认为这个是对的,有文献这么报道过,但是不是事实还有待于进一步研究和证实,不过我比较倾向于是.因为在线粒体中的某些蛋白就是由核DNA和mtDNA共同编码的,根据线粒体的内生共起源假说,就可以表明这个事实,不过目前这也只是个假说,所以还不好判断这句话的正确与否.
5.多彩的紫茉莉绿色叶片上的白斑是由于mtDNA变异导致电子传递障碍而产生的.
这句话肯定是错的.如果是mtDNA变异的话,电子传递发生障碍,那么该叶片就会死亡而不会产生白斑,这可能是与编码叶绿素的基因突变所致.另,转座子的作用实际也属于基因突变的范畴.
综上,最对的就是cpDNA is found in the chloroplasts.

1.非孟德尔遗传法则的遗传性状都是来自母系的核外遗传。
明显错误，摩尔根就是非孟德尔遗传，但它也是核物质遗传
2.这些分子用来进行编码光合作用的DNA和线粒体DNA。
这些分子是指什么？这个题有上文吗？是核外DNA？细菌的质粒就都不是这两个功能
3.cpDNA发现于叶绿体中
cpDNA就是叶绿体DNA ，The statement is true ！

好像不可以，有核膜和线粒体膜隔离
5.色彩斑斓的four o'clock 花瓣在绿色区域有白色斑点是由于线粒体DNA突变，电子传递板块
是线粒体的作用，但不一定是突变，可以是转座子的作用
翻译的不好，请指正
我的答案是 cpDNA is found in the chloroplasts
