The two types of nucleic acids are DNA which is double stranded and serves as the usual carrier of genetic information while RNA which is single stranded serves a carriers of genetic information in some viruses only.
Explanation:
They are hydrophobic. About 5 amino acids have polar side chains, R-groups which do not ionize or become positively or negatively charged. These R-groups are neither strongly hydrophilic nor hydrophobic. Atoms in long molecules, such as polypeptides, are not rigidly fixed in space or position
