To read the article, click on "First Human Chromosome Fully Sequenced".Most people might be surprised to learn that the human genome has not been fully sequenced. Gaps still remain that have not yet been bridged because of the nature of the DNA sequence coupled with past limitations on DNA sequencing technology. Nevertheless, a study has just been published using new and improved technologies that have allowed for the first complete sequence of a human chromosome.. . .Because the older style DNA sequencing produced very short snippets of sequence and certain regions of chromosomes had groups of DNA letters (words) that were repeated over and over, it was difficult to computationally reconstruct long contiguous repetitive DNA stretches. New, long-read technologies that produce extremely long snippets of DNA are now allowing these difficult regions to be traversed.
