Comparative biochemistry, by analyzing molecules like RNA and cytochrome, reveals evolutionary relationships between organisms due to similarities in their DNA or proteins.
Molekulalar (masalan, RNK va sitoxrom) boʻyicha biomolekulyar taqqoslashlar organizmlar orasidagi evolyutsion aloqalarni aniqlash uchun ishlatiladi, chunki ular koʻpincha oʻxshash DNK yoki proteinlarga ega boʻladi.

|---|---|
| Back | - some molecules rarely change (e.g RNA and cytochrome) rarely change and slight changes identify evolutionary links - neutral evo is where most variability in structure of molecule doesnt affect finction as most variability occurs outside functional regions, so not affected by natural selection - molecular sequences compared to discover how closley related organisms are, as they will have similar proteins/DNA |
