To determine:
What Botox is; how the cosmetic botulism toxin works; whether the treated muscles will be permanently frozen if the actor can get a systemic botulism infection from the treatment; and what caused the eyelids to sag.
Case summary:
In the given scenario, a 55-year old actor, concerned about maintaining his star status, wanted to remove the frown lines on his forehead. He asked his dermatologist about a cosmetic treatment to relax his facial lines and the dermatologist explained about the risks and benefits of Botox. The actor decided to have the treatment. Two weeks following the treatment, it was reported that his eyelids were sagging.

How are Eukaryotic cells different than Prokaryotic cells, in terms of evolution which form of the cell might have came first? How do Eukaryotic cells become malignant (cancerous)?arrow_forwardWhat are the roles of DNA and proteins inside of the cell? What are the building blocks or molecular components of the DNA and proteins? How are proteins produced within the cell? What connection is there between DNA, proteins, and the cell cycle? What is the relationship between DNA, proteins, and Cancer?arrow_forwardWhy cells go through various types of cell division and how eukaryotic cells control cell growth through the cell cycle control system?arrow_forward

- 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
