You've probably heard of the human genome,

我們已經完成了人類基因組定序，

Well, a genome is all the genes plus some extra

一個生物的基因組包括所有的基因

基因是由 DNA (脫氧核糖核酸) 組成，

and DNA is made up of long, paired strands

that your cells use to know how to behave.

Tissues cooperating with each other make organs.

器官的產生來自組織間的合作。

required the effort of hundreds of scientists

it will be possible to know the sequence of letters

Knowing the sequence of the billions of letters

and they're all packed together into a clump,

the long string of DNA down into smaller pieces.

Each of these pieces is then separated in space

if the sequences are the exact opposite of each other.

If the A-T-G-C sequence of two pieces of DNA

scientists use enzymes to make thousands of copies

A mixture of these special colored letters and enzymes

so we now have a double-stranded piece of DNA

are stitched together using computer programs

to create a complete sequence of the entire genome.
