DNA is a polymer, which means it is made of repeating subunits called monomers. What are the monomers of DNA called
The Correct Answer and Explanation is:
The monomers of DNA are called nucleotides. Each nucleotide consists of three components: a phosphate group, a five-carbon sugar (deoxyribose in DNA), and a nitrogenous base. The nitrogenous bases are classified into two categories: purines and pyrimidines. The purines are adenine (A) and guanine (G), while the pyrimidines are cytosine (C) and thymine (T).
DNA is a double-stranded molecule that forms a double helix structure. The two strands are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine, and guanine pairs with cytosine, following the base-pairing rules. This specific pairing is critical for DNA replication and transcription processes.
The structure of a nucleotide is the building block of DNA. When nucleotides link together, they form long chains through phosphodiester bonds between the phosphate group of one nucleotide and the sugar of the next. This forms the backbone of the DNA strand. The sequence of nitrogenous bases along a DNA strand encodes genetic information.
In summary, nucleotides are the monomers that make up DNA. These nucleotides join together to form long, repeating chains that encode genetic instructions for the growth, development, and functioning of living organisms. The specific sequence of nitrogenous bases in the DNA strand is what determines the genetic information carried by the molecule
