The Immortal Life of Henrietta Lacks Research the history of Henrietta Lacks to answer the following ten (10) questions: 1. What type of cancer did Henrietta Lacks die from? 2. Which type of infectious agent caused her cancer, what strain? 3. Does the infectious agent that caused her cancer cause a productive infection, latent infection, or both? 4. Which type of cytokine can recognize cells infected with the pathogen that caused her cancer? 5. Which type of particle recognition receptor...
7. Which enzyme was isolated from her(Henrietta Lack) cells to determine how embryonic cells divide rapidly?
Cancer cells often lack normal DNA damage response and cell-cycle control mechanisms. Why does this make them more susceptible to DNA-damaging chemotherapies? O Cancer cells will arrest in the cycle and will not grow further O Cancer cells with activating mutations in Ras will amplify the damage through the Ras signaling pathway Cancer cells might ignore the normal mechanisms that halt the cell cycle in response to damage, and subsequent division with damage leads to death, O Cancer cells have...
How do endocrine hormones affect their target cells? They cause changes in cell metabolism only. They stimulate the synthesis of glycogen. They increase the permeability of the target cell. They cause changes in cell metabolism and/or gene transcription. They affect gene transcription only.
Both proto-oncogenes and tumor suppressor genes help control the cell cycle. Genes called encode for cyclins that promote the cell cycle, while encode for cyclins that stop the cell cycle. Mutations within these genes cause cells to continue replication without regulation and form Both proto-oncogenes and tumor suppressor genes help control the cell cycle. Genes called encode for cyclins that promote the cell cycle, while encode for cyclins that stop the cell cycle.
How does a cell control the cell cycle? Explain 4 different ways that cell cycle is controlled.
Explain how the abnormal cell division of cancerous cells escapes normal cell cycle controls.
Cancer and Gene Regulation Why is a cell cycle control system needed for cell division? What happens when cells do NOT respond to the cell cycle control system and divide excessively?

List and describe chemical agents used in control of Explain three ways how pathogenic microbes cause diseases in their hosts. What are the main stages in the course of infection and disease? Explain the main events and characteristics for each of these stages. Explain the role of reservoirs and vectors in maintenance and spreading of infectious agents. What is the difference between mechanical and biological vectors? What are carriers? Explain endemic and sporadic diseases. What are epidemic and pandemic diseases?...
We did a cell migration experiment in Cell Biology Lab today to observe whether treated cells sped up, slowed down, or didn't affect migration. It looked like the treatment sped up cell migration. My question is can you give an example of a disease where this treatment might be helpful? How might it affect the disease?
