WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...

Bio 181 - Evolution Origin of Species - correct answer Descent with modification, natural selection, evolutionary adaptation, and evolution are the key components of this work by Charles Darwin. Descent with modification - correct answer Organisms related through descent from an ancestor. Natural selection - correct answer A population can change over time if individuals that possess certain traits leave more offspring than others. It is considered non-random because it deals with whateve...
