Significats de chordate en anglès

Then, one of those early deuterostomes became the very first chordate by gaining a notochord.

Over time, the chordate body plan gradually changed.

The larva of the invertebrate chordate Ciona intestinalis possesses only 36 striated muscle cells and lacks body segmentation.

In other words, we are vertebrates, which are a form of chordate, which are themselves a form of deuterostome.

Here we review the gene repertoire of Fads and Elovl in chordate genomes and the diversity of substrate specificities acquired during evolution.

Our results suggest that a duplication of a mono-CRD galectin gene gave rise to an original bi-CRD galectin gene, before or early in chordate evolution.

It is worth noting that this means that we ourselves are chordates.

The largest chordates are also the largest animals known to have existed: blue whales.

But the question of exactly where those first chordates came from has long proved controversial.

A sequence of duplication and divergence events of the different galectins in chordates is proposed.

A few living chordates still retain the ancient backbone-free condition where the notochord offers support.

Chordata All the animals pictured here are chordates.

There are over 64,000 living species, and many more known fossil chordates.

They belong in a more inclusive category called the chordates, which incorporates vertebrates and a few vertebrate-like groups.

Finally, cross-species comparisons between Ciona and the mouse evoke the deep evolutionary origins of cardiopharyngeal networks in chordates.

With the availability of an increasing number of whole genome sequences in chordates, exhaustive comparisons of multigene families become feasible.
