10 Questions
Explain the significance of cell biology in the field of biology and biomedical research.
Cell biology is important because all living organisms are made of cells, and understanding the structure, function, and behavior of cells is fundamental to all biological sciences. Additionally, insights gained from studying cell biology are essential for research in biomedical fields, such as cancer research.
What are some subtopics within the field of cell biology?
Some subtopics within cell biology may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.
What techniques are used in the study of cells?
The study of cells is performed using several microscopy techniques, cell culture, and cell fractionation.
Why is knowing the components and functions of cells fundamental to all biological sciences?
Knowing the components and functions of cells is fundamental to all biological sciences because all living organisms are made of cells, and understanding how cells work is essential to understanding larger organisms.
What is a cell and why is it considered the basic unit of life?
A cell is the basic unit of life responsible for the living and functioning of organisms. It is considered the basic unit of life because all living organisms are made of cells.
What is DNA repair?
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encodes its genome.
What causes DNA damage in human cells?
Both normal metabolic activities and environmental factors such as radiation can cause DNA damage.
How does DNA damage affect the cell's ability to transcribe genes?
Many of the lesions cause structural damage to the DNA molecule and can alter or eliminate the cell's ability to transcribe the gene that the affected DNA encodes.
What are the potential consequences of lesions that induce harmful mutations in the cell's genome?
These mutations can affect the survival of its daughter cells after mitosis.
What can occur when normal repair processes fail and cellular apoptosis does not occur?
Irreparable DNA damage may occur, including double-strand breaks and DNA crosslinkages (interstrand crosslinks or ICLs).
