Using the book as a model (section 39.2, "aminoacyl-trna synthetases have highly discriminating amino acid activation sites" and "proofreading by aminoacyl-trna synthetases increases the fidelity of protein synthesis", page 714 in third edition), explain how an alanine trna synthetase might prevent the incorrect addition of the similar amino acids glycine and valine to its target trna. true or falsehe alanine trna synthetase could have an activation site and an editing site, just like the threonyl-trna synthetase described in the book. - a. b. valine could fit in the activation site. - a. b. alanine could fit in the activation site. - a. b. glycine could fit in the activation site. - a. b. valine could fit in the editing site. - a. b. alanine could fit in the editing site. - a. b. glycine could fit in the editing site.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
