Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins.
These data are used worldwide in biomedical science, anthropology, forensics and other branches of science. Such genomic studies have led to advances in the diagnosis and treatment of diseases, and to new insights in many fields of biology, including human evolution.
2003, scientists reported the sequencing of 85% of the entire human genome, but as of 2020 at least 8% was still missing.Wikipedia
The total length of the human reference genome, that does not represent the sequence of any specific individual. The genome is organized into 22 paired chromosomes, termed autosomes, plus the 23rd pair of sex chromosomes (XX) in the female and (XY) in the male.

Protein-coding genes are distributed unevenly across the chromosomes, ranging from a few dozen to more than 2000, with an especially high gene density within chromosomes 1, 11, and 19.
