To determine: The effects of significant reduction of macrophages in the body.
Introduction: A complex network of cells, tissues, and organs that work collectively to protect the body and fight against the pathogens or foreign substances is called the immune system. Immune cells are the cells that actively participate in the defense mechanism initiated by the immune systems. One such major type of immune cells is lymphocytes.
To determine: Whether a significant decrease of macrophage or of memory B cells would have a greater effect on the immune system.

- What is the structure and function of Eukaryotic cells, including their organelles? 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
- In one paragraph show how atoms and they're structure are related to the structure of dna and proteins. Talk about what atoms are. what they're made of, why chemical bonding is important to DNA?arrow_forwardWhat are the structure and properties of atoms and chemical bonds (especially how they relate to DNA and proteins).arrow_forwardThe Sentinel Cell: Nature’s Answer to Cancer?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
