To determine: Whether increase in mitochondria in the muscle cells of people who endure sports is true or not.
Introduction: Physical activity often involves movement of the body and requires expenditure of energy. Muscle strengthening is a kind of physical activity that involves weight lifting, swimming, push ups, and other sports activities, which helps to increase the strength of bones and increase the muscle fitness.
To determine: The reason for increase in number of mitochondria in the muscle cells of those people who endure sports like marathon.
Introduction: Mitochondrion is an important organelle of the eukaryotes that are involved in the synthesis of energy rich molecules known as adenosine triphosphate (ATP). Due to this reason, they are known as “Powerhouse of the cell”.

- 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?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
