1·The scientists want to locate the position of the gene on a chromosome.

科学家们想找到该基因在染色体上的位置。《柯林斯英汉双解大词典》

2·The Chromosome is now losing important genetic information and is no longer functional.

染色体现在缺少重要的遗传信息，不再具有功能。

3·Every time the Chromosome divides—every time one cell divides into two—pieces of the ends of the Chromosome, the telomere, get broken off.

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。

4·Anyway, if we examine these ends of these coils of DNA, we will find a sequence of DNA at each end of every human Chromosome, called a telomere.

无论如何，如果我们检查这些螺旋状 DNA 的末端，我们会发现每条人类染色体的末端都有一个被称作“端粒”的 DNA 序列。

5·Most cells in your body have two copies of every chromosome and, therefore, two copies of every gene: one from your mother and one from your father.

你体内的大多数细胞每条染色体都有两份拷贝，因此，每个基因也都有两份拷贝：一份来自你的母亲，一份来自你的父亲。

6·Look at this rough drawing of one of them, one Chromosome about to divide into two.

看一下其中一条的草图，一条将要分裂成两条的染色体。

7·Abnormality of chromosome behavior occurs from premeiotic mitosis until various stages in meiosis.

从减数分裂前有丝分裂到减数分裂的各个阶段，染色体行为都会发生异常。

8·The results suggested that obvious difference of chromosome number appeared among theseAlnus species.

本次研究结果表明桤木属物种间染色体数目有明显的差异。

9·Centromere is the primary constriction on the chromosome, a region at which the sister chromatids are held together.

着丝点是染色体的主缢痕，在这个地方姐妹染色单体连在一起。

10·Do we have a chromosome like that?

那么我们真的有那么一条染色体么？
