In molecular biology and synthetic biology, one of the ultimate ambitions has long been the ability to design and construct entirely new living systems at the scale of whole genomes. With the rapid advancement of DNA sequencing and synthesis technologies, our ability to read and edit genetic sequences has greatly improved. However, most previous gene-editing techniques have relied on modifying DNA sequences that already exist in natural organisms. Designing a functional genome entirely from scratch has remained an enormous challenge.
DNA itself is composed of chains of four deoxyribonucleotide molecules, whose bases are adenine, thymine, cytosine, and guanine. For simplicity, these are commonly represented by the letters A, T, C, and G. For example, the coding region of the human β-actin gene contains 1,128 nucleotides arranged in a specific sequence.
