The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...

but in monomer A they are ordered through a crystal contact with a symmetry-related molecule. For residues 155–164 of loop L9 in molecule A, crystal contacts have the opposite effect ...

DNA is the molecular basis of heredity ... Polymers are made of monomers, and in DNA, these monomers are called nucleotides or nucleobases. The enzymes that handle DNA molecules are often called ...

Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. In the ...

A simple polyester can be made from a monomer which has two hydroxyl groups (-OH) and another monomer which has two carboxylic acid groups (-COOH).

Fractal patterns are found throughout nature on large, macroscopic scales, like in romanesco broccoli or fern plants, but ...

(PB) and acrylonitrile butadiene styrene (ABS) are widely used polymers in a number of products (including vehicle tires, ...
