| The primary categories for natural polymers include polysaccharides, proteins, nucleic acids, and polyisoprenes. |
| The nitrogen bases in the nucleic acids are joined via sugar linkages to long chains of alternating sugar and phosphate. |
| Nevertheless, the most optimal method for extracting nucleic acid must also be determined for each specimen type. |
| The C5 atom of cytidine bears a substantially larger negative charge than many nitrogen atoms in popular nucleic acid force fields. |
| However, reactive oxygen species generated by UVA radiation, particularly singlet oxygen, can also damage nucleic acids. |
| The unmodified biopolymers may be nucleic acids, polypeptides, proteins, carbohydrates, lipids and analogues thereof. |
