当异常半球中的神经元在成熟之前经历过多的细胞分裂时，就会发生这种罕见的疾病，即大脑一侧长得比另一侧大得多。
The rare disorder, in which one side of the brain grows substantially larger than the other, occurs when neurons in the abnormal hemisphere undergo too many cell divisions before they mature.
当每次染色体分裂时——即当每次一个细胞分裂成两个时——染色体的尾部，也就是端区，就会发生断裂。
Every time the Chromosome divides—every time one cell divides into two—pieces of the ends of the Chromosome, the telomere, get broken off.
结果表明，2,4 - D是诱导体细胞胚胎发生的关键因素，当培养基中只含2,4 - D而不含或少含细胞分裂素(6 -BA)时，外植体经由体细胞胚胎发生途径形成再生植株。
The results showed the explants could regenerate via somatic embryogenesis when the medium contained only 2, 4-d without or with little content of 6-ba.
