Deoxyribonucleotides within DNA contain deoxyribose as the pentose sugar. DNA contains the pyrimidines cytosine and thymine, and the purines adenine and guanine. Nucleotides are linked together by phosphodiester bonds between the 5ʹ phosphate group of one nucleotide and the 3ʹ hydroxyl group of another.

Proposed by Watson and Crick and validated by the Meselson-Stahl experiment, this process ensures each daughter DNA molecule consists of one old and one new strand, resulting in an "immortal strand" passed through generations. This mechanism is observed in both bacteria such as E. coli and eukaryotic organisms during chromosome replication.

Factors such as pH, salt concentration, and temperature can denature proteins. Some proteins can regain their shape and function when conditions return to normal, assisted by molecular chaperones. Ultimately, the amino acid sequence, governed by genes, dictates a protein's structure and function.
