Answer:
Step-by-step explanation:
The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.
Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.
Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.
