26. Nucleic Acids and Protein Synthesis

Draw the following phosphodiester bond based on the given description: A phosphodiester bond that connects the C3’ OH group in the ribose of UMP and the 5’ carbon in the ribose of CMP.

What nucleic acid subunits are connected in a phosphodiester linkage in a polynucleotide?

What is the name of the bond that joins nucleotides in a nucleic acid?

Cyclic ribose nucleotide phosphates, such as cyclic AMP (cAMP), are important signaling agents in living cells; all have the general structure shown here. What kind of linkage holds the phosphate to the ribose (see arrows; ribose is highlighted in blue)?

What is the difference between a phosphate diester and an ester of a diphosphate? Give an example of each.
