What is the difference (if any) between the structure of atp and the structure of the precursor of the a nucleotide in rna?

The correct answer will be- difference in the nitrogenous bases

Explanation:

Both ATP and RNA are ribonucleotides that are they are made up of a five-carbon sugar- ribose, a phosphate group and nitrogenous bases.

These two molecules differ in their nitrogenous bases as RNA is made up of four types of bases which could be adenine, cytosine, guanine and uracil whereas ATP is made up of adenine only. This is the difference in the structure of the precursor of the RNA molecule and ATP.

Thus, the difference in the nitrogenous bases is the correct answer.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
