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.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
