Differences could be listed as,

DNA : (a) Is a gene carrier. (b) It has two chains in its structure (c) contains codes for many protein synthesis

Proteins : (a) single identity molecule (b) gets denatured easily (c) does not carry genetic information

Similarities could be listed as,

Both of them are composed (a) basic amino acids (b) can be broken down into smaller fragments (c) arrangement of amino acids/bases determines the final function greatly.
