Each person's DNA consists of about 6 billion base pairs stored in 23 pairs of chromosomes— 46 total.

每个人的 DNA 由大约 60 亿个碱基组成，存储在 23 染色体中——总共 46 条。

It's found on chromosome 4 and you can tell like how many base pairs, it's 6000 letters long.

它位于4号染色体上，你可以道它有多少碱基，长度为6000个字母。

They managed to insert this 765 base pair segment of DNA into the yeast genome, right?

他们设法将这 765 个碱基的 DNA 片段插入酵母基因组中，吧？

And some parts, particularly those where the same short pattern of base pairs is repeated over and over again, remain difficult to sequence well.

而且其中某些部分，尤其是那些短型碱基被不断复制的位置，仍然很难准确测序。

When Huda and Harry combined their data, they were able to narrow the location of their gene down to about one million base pairs.

Huda 和 Harry 合并数据后，他们就能将基因位置缩小到大概100万碱基内。

Besides the low error rate, Dr Kedes requires that the sequence be complete-meaning that it includes at least 98% of the genome's base pairs.

除了错误率要低，科德斯博士还要求测序结果必须是完整的，即至少包括人体98%的染色体碱基。

Rather than patenting every conceivable variant, the company claims jurisdiction over isolated DNA sequences, 15 base pairs long, that match short parts of the genes.

他们不是每一有可能得到的基因突变体持有专利权，而是一段分离到的基因序列持有专利权，这段基因序列含有15个碱基。

Alright, so the dystrophin gene is a huge gene on the X-chromosome, that has 79 exons and is over 2 million base pairs in length.

抗肌萎缩蛋白基因是X染色体上一个庞大的基因，含有79个外显子，全长超过2000kbp（书上通常缩写为bp，碱基）。
