Amorphous solids do not have a definite melting point or regular repeating units. An amorphous solid is a solid in which there is no long-range order of the positions of the atoms unlike those in crystalline solids. An example of an amorphous solid is window glass. In addition many polymers such as polystyrene are amorphous.
DNA is not made up out of 2, but 4 repeating units. These repeating units, nucleotides, being Adenine, Thymine, Guanine, and Cytosine.
No
A crystal has an orderly repeating pattern of atoms, so does a polymer. The term "polymer" is usually reserved to describe a substance with a repeating pattern of formula units (monomers) which are groups of atoms.
I do believe you are asking about a sarcomere, units of repeating bands that make up the fibers (myofibrils) of a striated muscle.
