 Chromosome 19:  l'un des 22 autosomes.

Livermore researchers chose chromosome 19 to study because, of all 23 human chromosomes, it has the highest concentration of guanine–cytosine base pairs, long thought to imply a higher concentration of genes. That hunch proved to be correct. “The density of genes on chromosome 19 is one of the highest of all chromosomes,” says Livermore biomedical scientist Laurie Gordon.
One early Livermore research project examined three genes on chromosome 19 that are involved in the repair of DNA damaged by radiation and environmental pollutants. DNA repair genes produce proteins that “cruise” the length of DNA, removing unwanted proteins and looking for any mistakes that might disrupt the smooth functioning of a cell. These repair gene studies, which still continue, may lead to insights about the development of cancers, many of which are caused by defects in DNA repair pathways. Another Livermore project studied a family of about 60 genes on chromosome 19 involved in detoxifying and excreting chemicals foreign to the human body.....

Olsen says that chromosome 19 was not easy to map. It contains a large number of repetitive sequences that are interspersed throughout its DNA. Another factor, which complicated accurate sequencing later on, is that the chromosome is more tightly bonded than other chromosomes because of its high instances of guanine–cytosine bonds. As a result, a single strand of the double-stranded molecule can loop back on itself to form confusing secondary structures.....

One group of genes that has duplicated especially frequently is called zinc finger genes, which produce proteins that bind to elements allowing them to regulate the activity levels of other genes. A significant fraction of the roughly 800 human zinc finger genes are found on chromosome 19.....


Many researchers, even those who have retired, still have strong feelings about chromosome 19. “Those of us who have worked with chromosome 19 for so many years have an emotional attachment to it,” says Olsen.

De nombreux chercheurs, même ceux qui ont pris leur retraite, ont encore des sentiments forts sur le chromosome 19. «Ceux d'entre nous qui ont travaillé avec le chromosome 19 depuis tant d'années ont un attachement émotif à elle», dit Olsen.

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 19, one copy inherited from each parent, form one of the pairs. Chromosome 19 spans about 59 million base pairs (the building blocks of DNA) and represents almost 2 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 19 likely contains about 1,500 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body.

Genes on chromosome 19 are among the estimated 20,000 to 25,000 total genes in the human genome.
