Yes, scientists have sequenced the entire human genome, but they're not done yet

The human genome, from end to end, has been sequenced, meaning scientists worldwide have identified most of the nearly 20,000 protein-coding genes. However, an international group of scientists notes there's more work to be done. The scientists point out that even though we have nearly converged on the identities of the 20,000 genes, the genes can be cut and spliced to create approximately 100,000 proteins, and gene experts are far from agreement on what those 100,000 proteins are.
