16s rRNA is also large enough to retain organism-specific information, but small enough to be manageably sequenced in a reasonable amount of time.
It remains unclear which reaction (CAS/CYS) of Tu-CAS provides the strongest adaptive advantage, but the CYS activity might be one of the reasons why these horizontally transferred genes have been retained in organisms that are at present not living on cyanogenic plants.
Also, the surface topography of the denture has been shown to greatly influence adhesion and subsequent retention, with more roughened surfaces retaining more organisms [ 17– 17].
Marine organisms retained and sometimes expanded their seleno-proteomes, whereas the seleno-proteomes of some terrestrial organisms were reduced or completely lost.
Nevertheless, many clues to the numerous gradations that occurred during eye evolution are retained in surviving organisms in the morphology and biochemistry of their retinal cells and, perhaps most importantly, in their genes.
Although fulminate infections result from a profoundly suppressed host immune system, some immune function is retained and the organisms must evade this response.
This exact peptide sequence was found to exist in both mouse and rat protein homologues, and alignments of these sequences found that the specified intron is retained in both organisms, encoding an additional 37 additional amino acids (Figure 2).
In most prokaryotic phyla, organisms retained Ni and/or Co utilization traits.
Overlap between UTRs is preferentially retained in all organisms, while the overlap between coding regions and introns is common in zebrafish, drosophila and worm.
Thus, all the amino acid replacements that we performed at NDUFC2 position 46 were previously chosen during evolution and were successfully retained in living organisms.
