Bacteria are extremely efficient organisms. Which one of the following characteristics describes this efficiency in relation to protein production?
1)Bacteria are polycistronic and have multiple different genes on one mRNA.
2)Every gene is always turned on so that proteins are produced at a rapid rate.
3)Bacteria have multiple different types of polymerases for each gene.
4)Every gene has an activator that is necessary to begin translation so the cell doesn’t waste energy producing unnecessary proteins.
A 45 year-old woman complaining of breast pain was diagnosed with having HER2-positive breast cancer. The patient underwent lumpectomy followed by a period of chemotherapy including adjuvant treatment. Over the course of their treatment, the patient developed a urinary tract infection that required antimicrobial therapy, which initially consisted of atrimethoprim / sulfametoxazole combination drug. However, the patient during the course of her therapy suffered multiple recurrent infections and was, consequently, enrolled in a clinical trial to test the efficacy of a new mannoside anti-infective agent. Question: With reference to signaling pathways, discuss the pathogenesis of HER2-positive breast cancer. In your answer, include discussion on the differential diagnosis of this condition.
What gives shape to bacteria cell
What is the difference in the function of the glycoprotein structures of an HIV virion and the cilia of an animal cell?
•Choose four organelles of the cell
•Create an analogy using a real life scenario describing what these organelles might represent
•In one to two paragraphs, I need to describe how these organelles would function as real-life objects and compare them to the organelles in the cell. AND answer the conclusion question; What is the importance of the organelles working together to perform functions in the cell?
