WebAzathioprine is a drug that may be prescribed to transplant recipients to reduce the chance of tissue rejection reactions. In its active state, it acts as a purine analogue, inhibiting DNA biosynthesis. This means that 6-mercaptopurine will be inserted in place of a purine containing nucleotides during DNA replication. WebRNA molecules are created during a process called transcription. This process uses the enzyme RNA polymerase to transcribe segments of DNA into complementary RNA molecules. First the RNA polymerase binds to a promoter region of the DNA to initiate transcription. Then the mRNA is transported from the nucleus to the cytoplasm.
