Answer 1

1) Proteins. In proteins, shape of the molecule is very important to define its function. Depending on the type of structure a protein molecule forms, it's functtion is designated such as whether it will be a structural protein or form an enzyme or it will form a membranme channel etc.

2) Uracil. It is one of the nitrogenous bases found in RNA. Typically a nucleotide is composed of Pentose sugar (ribose/deoxyribose) + Phosphate + Nitrogenous base

3) Secondary, tertiary and quaternary structures of protein may use hydrogen bonding. Hydrogen bonding is typically used for stabilization of the protein structure In secondary structure, conformation of the protein is based on the hydrogen bonding pattern as to whether it will form a helix structure or a sheet structure.
