To understand Sanger sequencing, one must first understand how to synthesize DNA. As we stated in Section 1.1.1, DNA is built up from building blocks that we called nucleotides, more specifically deoxynucleotide triphosphates or dNTPs. These dNTPs are made up of a sugar (deoxyribose), a nucleobase (A, T, G or C) and 3 phosphate groups. By successively adding these dNTPs at the end of an existing DNA molecule, we extend it, linking one of the phospates of the dNTP to an oxygen atom on the last nucleotide of the DNA molecule. Let us now consider a dideoxynucleotide triphosphate (ddNTP), which is identical to a dNTP except we remove a specific oxygen atom. This ddNTP can be added to the growing molecule of DNA like regular dNTPs, but since it is missing that one oxygen atom no more dNTPs or ddNTPs can be added to the DNA molecule after this one. The elongation is terminated and we call these ddNTPs chain-terminators. This combination of DNA synthesis followed by termination are at the heart of Sanger sequencing.,推荐阅读谷歌浏览器获取更多信息

That worked great for our early customers when there were only two of us writing code and each of us owned a huge portion of it and knew everything. After we started hiring, it became a disaster. Bugs were appearing everywhere out of the blue. The codebase was a huge mess of nulls, undefined behaviour, bad error handling. It was so bad that we actually lost a client over this.
