Summary Introduction

Introduction:

An element is a substance that cannot be separated or converted into a simpler form. All matter in the environment is formed from a combination of different elements or same elements. An atom is the smallest unit of an element and each atom contains all the properties of that element. Atoms are composed of subatomic particles which include electrons, protons, and neutrons. The mass number of an element is equal to the mass of its atom’s protons and neutrons.

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?
