Question
Chapter 15, Problem 4PDT
Summary Introduction
To explain: The reason the evolutionary biologists maintain that modification of existing traits and the evolution of novel characters have proceeded by successive small steps.
Introduction: Evolution can be defined as the change in hereditary characteristics of biological populations over generations. It involves the inculcation of novel characteristics or traits over time. Evolution is based on the idea that all species are related and gradually change over a period of time.

Molecular Biology Question
You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?
