Teams of computer scientists and biology students work together to develop a simulated experiment on mutations in mice. The simulation is programmed with the complete sequence of mouse DNA. Then it calculates the frequency of mutations under three conditions: when the mice are subjected to tobacco smoke, subjected to ultraviolet radiation, and kept under normal conditions. For each mutation, the simulation identifies whether the mutation affects a mouse protein. The biology students prepare the data table shown below to organize the results of the simulation. Conditions Frequency of Mutations (altered DNA base pairs) Percent of Mutations that Affect Proteins Normal Tobaco Smoke Ultraviolet Light What is the independent variable of the simulated experiment?

If scientists are wrong about earth's age based on radioactive material and the decay rates are really much faster, how would nuclear power plants be affected?

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna. nothing should be altered. the ph should be decreased. the temperature should be raised.
