Telechelic polymer. A telechelic polymer or oligomer is a prepolymer capable of entering into further polymerization or other reactions through its reactive end-groups. It can be used for example to synthesize block copolymers. By definition, a telechelic polymer is a di-end-functional polymer where both ends possess the same functionality. Where the chain-ends of the polymer are not of the same functionality they are termed di-end-functional polymers.
The cause of Tay-Sachs disease is a genetic defect (mutation) that is passed from parent to child. This genetic defect is located in the HEXA gene, which is found on chromosome 15.The HEXA gene makes part of an enzyme called beta-hexosaminidase A, which plays a critical role in the nervous system.he cause of Tay-Sachs disease is a genetic defect (mutation) that is passed from parent to child.

Tay-Sachs disease and resistance to tuberculosis. Tay-Sachs is a rare genetic disease that results in an abnormal accumulation of neuronal lipids caused by a defective lysosomal enzyme, Î±-hexosaminidase. Alleles for this disease are more prevalent in certain populations, the most well-known being the Ashkenazi Jews.t is of note that a particular genetic disorder leads to infectious disease hypersusceptibility, and this relationship has provided the basis for a preventative. Specifically, the relationship between hemosiderosis and typhoid fever has led to the development of a vaccine that intervenes in this relationship.
