In genome sequencing, “complete” usually means “almost complete.” For example, genomes that we usually call complete usually omit repetitive DNA segments, which are usually scanned in short, hard-to-piece-together segments. Not content with “usually,” a large group of genomic researchers decided to try something different.
The researchers, representing the National Human Genome Research Institute (NHGRI) and other institutions, made a point of sequencing an X chromosome from end to end—from telomere to telomere—without missing any highly repetitive DNA.
