SURVEY AND SUMMARY Did DNA replication evolve twice independently?
DNA replication is central to all extant cellular organisms. There are substantial functional similarities between the bacterial and the archaeal/eukaryotic replication machineries, including but not limited to defined origins, replication bidirectionality, RNA primers and leading and lagging strand synthesis. However, several core components of the bacterial replication machinery are unrelated...
متن کاملDid the ctenophore nervous system evolve independently?
Recent evidence supports the placement of ctenophores as the most distant relative to all other animals. This revised animal tree means that either the ancestor of all animals possessed neurons (and that sponges and placozoans apparently lost them) or that ctenophores developed them independently. Differentiating between these possibilities is important not only from a historical perspective, b...
متن کاملDid auditory sensitivity and vocalization evolve independently in otophysan fishes?
Otophysine fishes have a series of bones, the Weberian ossicles, which acoustically couple the swimbladder to the inner ear. These fishes have evolved a diversity of sound-generating organs and acoustic signals, although some species, such as the goldfish, are not known to be vocal. Utilizing a recently developed auditory brainstem response (ABR)-recording technique, the auditory sensitivities ...
متن کاملHow Did T3S Evolve?
The injectisome has a common evolutionary origin with the bacterial flagellum, as suggested by the fact that the basal bodies of both nanomachines are similar and include many proteins with a significant similarity. Moreover, there are also functional similarities, such as the use of specific chaperones (5, 45, 104, 108, 138) or of molecular systems regulating the size of the external appendage...
