Telomeres are sections of noncoding, repeating DNA that protect chromosome ends.

端粒是保护染色体末端的非编码重复DNA序列。

Pachytene FISH results showed that most of chromosome ends possess the telomere tandem repeats, but the signals on different chromosomes were not the same in intensity.

粗线期染色体荧光原位杂交结果表明，大多数染色体的末端都有端粒串联重复，但信号的强度在不同染色体上是不同的。

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。

The research team was also recognized for its discovery of telomerase, which is the enzyme that causes the chromosome ends to stay intact when they divide.

The signals that indicate where the copying machinery should start and stop, which is a good working definition of where on a chromosome a gene begins and ends, are imperfectly understood.
