What is Chromosome 19?
Chromosome 19 meaning 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.
