Sol.
As we know, nucleic acids are not homopolymers but these are heteropolymers made up of different types of nucleotides connected to each other through phosphodiester linkage.
So, option 1 is incorrect.
It is a fact that every polymerized monomer unit carries a negative charge at physiological pH (6.5-8.0).
So, option 2 is correct.
Also, we know that successive units in nucleic acids are connected through a phosphodiester linkage.
So, option 3 is correct.
We know that, RNA and DNA are not strong acids rather these are weak acids.
So, option 4 is also incorrect.
Hence, first option i.e. 2 and 3 is the correct answer for this question.
