Consider the case of in vitro evolution used to generate RNA molecules with ligase activity. If the researchers repeated the inv
estigation using a higher fidelity DNA polymerase during PCR, the _______ would most likely be _______. A. selection intensity; higherB. selection intensity; lowerC. population size; higherD. mutation rate; higherE. mutation rate; lower
In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.
And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.
So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. ... Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.
The correct answer for this question is this one: C:"It provides support." There exists the same question with the same choices. The function of the cell structure that is labeled X is that it provides support.
