Other claims from this paper (5)
- Association Ribosomal protein composition varies among eukaryotic organisms and dissimilarity correlates with taxonomic distance.
- Observation Plant cytoplasmic and organellar ribosomes have highly dissimilar protein complements.
- Observation Chloroplast ribosomes differ more among distantly related plants than cytoplasmic ribosomes.
- Observation Higher plant organellar and cytoplasmic ribosomes resemble bacterial and animal ribosomes respectively in acidic proteins and protein distribution between subunits.
- Mechanism Plastid genome coding calculations support plastid DNA encoding chloroplast ribosomal structural proteins under stated assumptions.
