Question

What is phosphodiester bond ? Explain competitive inhibition by given an example ?

Answer 1

Answer:

the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.

In competitive inhibition, an inhibitor that resembles the normal substrate binds to the enzyme, usually at the active site, and prevents the substrate from binding. ... For example, methotrexate is a chemotherapy drug that acts as a competitive inhibitor.
