Australian Jack Irishâex-lawyer and sometime debt collector, cabinetmaker and barflyâgets a double introduction as MacAdam/Cage releases his first two adventures (number two is Black Tide) this month.
But ever since then, the estimated number has been steadily shrinking. A new study suggests that the human genome could contain as few as 19,000 protein-coding genes, fewer than nematode worms. In 2001, the initial sequence of the human genome cut the figure dramatically.
A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before.he hemoglobin gene, HBB, is found on chromosome 11. This chromosome is a little less than 135 million DNA letters long and HBB is just one of its over 1500 different genes. Chromosome 11 is definitely one of the most gene-rich chromosomes we have.
