Review Questions

• How do the characteristics of mammalian cells make them suitable for research applications?
  • Mammalian cells possess eukaryotic features such as a defined nucleus and organelles, which enable them to perform complex biological functions similar to human cells. This similarity allows researchers to study disease mechanisms, test drug responses, and understand cellular processes in a controlled environment. Their ability to grow in culture further enhances their utility in various experiments and biotechnological applications.
• Discuss the importance of post-translational modifications in mammalian cells and how they affect protein function.
  • Post-translational modifications are crucial for the proper functioning of proteins synthesized by mammalian cells. These modifications can alter protein stability, activity, localization, and interactions with other molecules. For instance, phosphorylation can activate or deactivate enzymes, while glycosylation can affect protein recognition during cell-cell interactions. Understanding these modifications helps researchers design more effective therapeutic strategies.
• Evaluate the impact of mammalian cell culture techniques on the development of therapeutic agents and personalized medicine.
  • Mammalian cell culture techniques have revolutionized the way therapeutic agents are developed by providing a platform to test drug efficacy and safety in a controlled setting. These techniques allow for the modeling of human diseases using patient-derived cells, leading to personalized medicine approaches tailored to individual responses. The ability to manipulate these cultures enhances our understanding of drug interactions at the cellular level, paving the way for targeted therapies that improve patient outcomes.
