Question

multiple choice question
polyphosphate granules store the phosphate needed for synthesis of ______.

○ dna and rna
○ internal membranes
○ peptidoglycan
○ the cytoskeleton

Explanation:

Phosphate is a key component of nucleotides, which are the building blocks of DNA and RNA. Polyphosphate granules store phosphate, and this stored phosphate is used in the synthesis of nucleic acids (DNA and RNA). Internal membranes are mainly composed of lipids, peptidoglycan is a component of bacterial cell walls (composed of sugars and amino acids), and the cytoskeleton is made of proteins, none of which rely on phosphate from polyphosphate granules for their synthesis.

Answer:

A. DNA and RNA
