Nucleotides
Four nucleotides are needed to make a DNA molecule.
Four nucleotide subunits are needed to make a DNA molecule: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides form complementary base pairs (A-T and C-G) that allow DNA to replicate and encode genetic information.

A polymer is a large molecule made up of identical or similar subunits linked together. Examples of polymers include proteins, DNA, and carbohydrates.
The subunits that make up DNA are called nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).
Two monosaccharides are needed to form one maltose molecule. Specifically, maltose is comprised of two glucose molecules joined together through a condensation reaction, which releases a molecule of water.
Hemoglobin contain iron.
Water. H2O is where the hydrogen comes from to build the C6H12O6 molecule.
The subunits making up nucleic acids are nucleotides
The repeating subunits of DNA and RNA are called nucleotides. Nucleotides are composed of a phosphate group, a sugar molecule (deoxyribose in DNA and ribose in RNA), and a nitrogenous base (Adenine, Thymine, Cytosine, and Guanine in DNA; Uracil replaces Thymine in RNA).
nucleotides
Amino acids are the subunits that make up proteins.
The subunits that make up polysaccharides are sugars, or monosaccharides. An example of a monosaccharide is glucose, which we need for energy.
