Question

DNA is a polymer of _______.

Answer 1

DNA (deoxyribonucleic acid):

1. It is an organic chemical, which comprises instructions and genetic information for the synthesis of protein.
2. It is found in the majority of the living species.
3. The majority of the molecules of DNA comprise two biopolymer strands wrapped around each other to produce a double helix.
4. The two strands of DNA are called polynucleotides as they comprise simpler units known as nucleotides.
5. Each nucleotide comprises nitrogen-containing nucleobases, that is, either adenine, guanine, cytosine, or thymine, as well as deoxyribose sugar and a phosphate group.
6. The nucleotides are associated with each other with the help of covalent bonds between the phosphate of one nucleotide with the sugar of the next, leading to the formation of an alternating sugar-phosphate backbone.
7. Therefore, it can be said that nucleotides are the building blocks of DNA.

Final answer: DNA is a polymer of nucleotides.
