Enzymes. They don't need it
Because it's partially permeable membrane so it won't let anything get inside the leaf so by this cuticle the leaf is protected not to let any foreign substances in and preventing loss of water
They are soluble. Often, they are of an appropriate polarity and size as well.
<span>Proteins are large biological molecules consisting of one or more chains of amino acids. Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job.
</span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.

Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>
Phenotype? I think that's it
