Definition
| He studied subunit ribosomal RNA (rRNA) and found that the more similar the sequence of (AUCG) rRNA, the closer the organism is related. This scientist, along with colleagues, began assigning organisms based on their closely related rRNA instead of grouping them based on characteristics such as the presence of a nucleus. |
