Scientists have produced a complete map of the human chromosomes nine and 10, which are linked to diseases including cancer, diabetes and Alzheimer’s, according to Nature magazine. An international consortium of public scientists announced last year they had completed what was called the Human Genome Project (news - web sites), producing a map of 95 percent of the human genetic code. Work continues, however, to decipher the function of the estimated 30,000 to 40,000 genes that encode more than 10 times that number of proteins to make a human being. This latest work brings to nine the number of human chromosomes which have been fully sequenced and analysed. Humans have a total of 46 chromosomes -- 22 pairs plus two sexual chromosomes.
