What macromolecule is made up of nucleic acids? a. protein b. fructose c. dna d. triglyceride

C. DNA

Explanation:

DNA (deoxyribonucleic acid) is the genetic material present in nucleus of eukaryotes and nucleoid of prokaryotes. Nucleic acids are the polymers of nucleotides. Two types of nucelic acids are RNA (ribonucleotide nucleic acid) and DNA.  

DNA is also a polymer of deoxyribonucleotides all of which have a nitrogenous base, phosphate molecule and pentose sugar. This makes option C correct answer.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
