WebVandaag · Primarily, drugs interact with biological macromolecules (protein/DNA/RNA) in the human body to alter the physiological function and produce the desired effect. Drugs perform specific acts by interfering with macromolecules and altering cellular or biochemical processes, often called ‘drug targets.’ WebRNA polymerase works by catalyzing the nucleophilic attack of 3’ OH of RNA to the alpha phosphate of a complementary NTP molecule to create a growing strand of RNA from the template strand of DNA. Furthermore, RNA polymerase also displays exonuclease activities, meaning that if improper base pairing is detected, it can cut out the incorrect …
