The repeating unit of a double helix, such as that of DNA, consists of three main parts: a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine). These components form the backbone of the helix through phosphate-sugar linkages, while the nitrogenous bases pair in specific combinations (A with T and C with G) to create the genetic code. Together, they contribute to the structural integrity and function of the DNA molecule.
The repeating group of atoms in a crystal is called a unit cell. This unit cell is the smallest repeating structure that can be used to build up the entire crystal lattice.
A monomer.
The repeating unit in polypropylene is derived from propylene monomers, which have the chemical structure CH2=CH-CH3. When polymerized, the double bond between the carbon atoms opens up, allowing the monomers to link together in a chain. This results in a structure characterized by a backbone of carbon atoms with alternating methyl groups (–CH3) along the chain, giving polypropylene its unique properties. The general formula for the repeating unit is –(C3H6)–, representing the propylene units in the polymer chain.
The repeating unit for polyvinyl chloride (PVC) is -CH2-CHCl-.
