The answer is: All nucleotides have a phosphorus atom that can be replaced with 32P.
DNA building blocks are nucleotides. Nucleotides contain a nitrogenous base, a five-carbon sugar, and, at least, one phosphate group. Exactly that phosphate group in the nucleotide has the phosphorus atom. Therefore, the phosphorus atom in the nucleotide can be replaced with radioactive phosphorus-32 (32P). This replacement has a wide use in labeling nucleic acids and thereby visualizing the target molecule.

Proteins store energy long term, provide lubrication, and insulate the body
Proteins in the form of enzymes catalyze chemical reactions
Proteins provide structures in the body, such as hair and muscles
Proteins in the cell membrane help transport substances into and out of cells
Answer:
Proteins store energy long term, provide lubrication, and insulate the body
Explanation:
Proteins store energy long term, provide lubrication, and insulate the body - this is false, this describes the role of fats.
Proteins in the form of enzymes catalyze chemical reactions - this is true, enzymes are an important class of proteins in the body
Proteins provide structures in the body, such as hair and muscles - this is true, for example our hair is made of a protein called keratin
Proteins in the cell membrane help transport substances into and out of cells - this is true, proteins form important pumps and channels in the cell membrane
