What is apoptosis?

a. an experimental technique used to kill specific cells

b. programmed cell death that is required for normal development

c. a pathological condition observed only in damaged or diseased organisms

d. a developmental mechanism unique to the roundworm C. elegans

Expert Solution & Answer

Summary Introduction

Introduction:

Usually, cells produce signals that trigger them to differentiate and divide. Apoptosis is a phenomenon that occurs in multicellular organisms in a programmed and controlled manner, where cells die as a result of a signal triggering death.

Answer to Problem 1TYK

Correct answer:

Apoptosis is defined as the process where the cell death is already programmed, which is a controlled and normal process.

Explanation of Solution

Explanation/Justification for the correct answer:

Option (b) is given that apoptosis is programmed cell death, which is necessary and is carried out for normal development of the organism. It is a programmed process and is highly regulated for normal functioning of body and immune cells and normal cell turnover. Hence, Option (b) is correct.

Explanation for incorrect answers:

Option (a) is given that apoptosis is an experimental technique used to kill specific cells. The apoptosis is not an experimental technique used to kill only specific cells; instead, it is a programmed process and is carried out by most of the normal cells. So, it is a wrong answer.

Option (c) is given that apoptosis is a pathological condition observed only in the damaged or diseased organism. The apoptosis is not a pathological condition observed in diseased tissue and has a controlled mechanism. So, it is a wrong answer.

Option (d) is given that apoptosis is a developmental mechanism unique to the roundworm Caenorhabditis elegans. Caenorhabditis elegans is a pseudocoelomate, which lacks a circulatory and a respiratory system. The apoptosis process is not a developmental mechanism of Caenorhabditis elegans. So, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Thus, apoptosis is the programmed cell death in an organism.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
