测序技术在人类基因组计划后有了长足的进展，但是它仍然要求DNA经过一项称为“放大”的步骤，被复制几百万次，然后再用荧光标记。

Sequencing technology has come a long way since the Human Genome Project, but it still requires DNA to be copied millions of times, a step called amplification, and labelled with fluorescent tags.

因此对其知识的缺失也映证了为什么2004年完成的人类基因组测序在某种程度上说并未能实现之前期待的结果。

That missing knowledge could explain why the human genome's sequencing, finished in 2004, has in some ways failed to fulfill its public expectations.

但是从那时此，技术水平得到了显著的提升：现在只需八天和10000美元就进行一次人类基因组测序成为了可能。

The technology has improved enormously since then: it is now possible to sequence a human genome in about eight days, at a cost of around $10,000.
