. Suppose you modify the glycine-tRNA so that the glycine is changed to valine. Based on the results of the Benzer experiments, because the protein synthesis machinery recognizes the . proteins would have valines where glycines normally are; tRNA anticodon proteins would have glycines where valines normally are; amino acid attached to the tRNA nothing should change in proteins; amino acid attached to the tRNA proteins would have valines where glycines normally are; amino acid attached to the tRNA nothing should change in proteins; tRNA anticodon

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
