WebbThe OCA2 gene is located on the segment of chromosome 15 that is often deleted in people with this disorder. However, loss of the OCA2 gene does not cause the other signs and symptoms of Prader-Willi syndrome. The protein produced from this gene helps determine the coloring (pigmentation) of the skin, hair, and eyes. WebbChromosomes. DNA strands are packaged into chromosomes with proteins, which allow cells to control gene expression (and phenotypes), replication of the DNA, and separation of the genetic material into cells as they divide. Most (but not all) Bacteria and Archaea have circular chromosomes, with the DNA strands forming a continuous loop.
