How doesSofosbuvir work?

DNA isthe hereditary material in humans and almost all other organisms. An importantproperty of DNA is that it can replicate or makes a copy of itself. 

RNA isone of the all known forms of life. It plays an important role in regulatingcellular processes from cell division, differentiation, and growth to cellaging and death. 

Thismedication works by blocking the action of an enzyme called NS5B RNA-dependentRNA polymerase in the hepatitis C virus. In which the virus needs to grow. Thisstops the hepatitis C virus from increasing, which lowers the amount ofhepatitis C virus in the liver. This helps to decrease liver damage andprogresses or improves the function of the liver.
