In Conversation with Dr. Adam Phillippy

Dr. Adam Phillippy answers questions about the first complete DNA sequence of a human chromosome. The results, published in the journal Nature, show that generating a precise, base-by-base sequence of a human chromosome is now possible, and will enable researchers to produce a complete sequence of the human genome. After nearly two decades of improvements, the reference sequence of the human genome is the most accurate and complete vertebrate genome sequence ever produced. However, there are hundreds of gaps or missing DNA sequences that are unknown. These gaps most often contain repetitive DNA segments that are exceptionally difficult to sequence. Yet, these repetitive segments include genes and other functional elements that may be relevant to human health and disease.
