Answer:

DNA is made of repeating units of building blocks called nucleotides.

Explanation:

There are four nucleotides in the DNA, the guanine and thymine, adenine and cytosine. Guanine binds with cytosine and adenine binds with thymine.

These nucleotides are made of deoxyribose sugar that binds to a phosphate and a nitrogenous base.  

Answer: DNA is made up of repeating units of building blocks called nucleotides.

Explanation.

Deoxyribonucleic acid(DNA) is a long polymer made up of repeating units building blocks called nucleotides. Nucleotides is the organic building block of DNA and it consist of sub unit molecules, a nitrogenous base called nucleobase, a six carbon sugar called deoxyribose and a phosphate group. The bases use in DNA are adenine(A), cytosine(C), thymine(T) and guanine(G). Nucleotide is important for cellular metabolism.
