What is a change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals called?
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals is called a mutation. Mutations can lead to variations in genes and can sometimes result in negative effects on an organism's traits or health.
What causes mutations?
sunlight, radiation, and smoking
What is chromosomal imbalance?
Chromosomal imbalance refers to an abnormality in the number or structure of chromosomes in an individual's cells. This can be due to errors during cell division, exposure to certain chemicals or radiation, or genetic conditions. Chromosomal imbalances can lead to various health issues and developmental disorders.
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals?
A mutation is a change in the DNA sequence that can occur due to errors in DNA replication, exposure to radiation, or chemicals. Mutations can have various effects on an organism, such as causing genetic disorders or contributing to evolutionary changes.
What causes the deletion of chromosome 5?
Deletion of chromosome 5 can be caused by genetics mutations during cell division, exposure to certain chemicals or radiation, or spontaneous errors in DNA replication. It can also be inherited from a parent who carries a chromosomal abnormality.
What can cause mutation when the cell copies its DNA?
i seriously dont know.. in error, exposure to chemicals and exposure to radiation
What does the process of carcinogenesis usually begin with?
Carcinogenesis usually begins with the accumulation of genetic mutations in a cell that lead to uncontrolled cell growth and division. These mutations can be caused by various factors such as exposure to carcinogens, radiation, or viruses.
What is a change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals called?
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals is called a mutation. Mutations can lead to variations in genes and can sometimes result in negative effects on an organism's traits or health.
Tobacco smoke contains chemicals which make cells divide too much and a serious disease may occur?
Yes, tobacco smoke contains harmful chemicals such as carcinogens that can damage cells, leading to uncontrolled cell division and potentially causing cancer. Prolonged exposure to these chemicals increases the risk of developing serious diseases like lung cancer, throat cancer, and cardiovascular diseases. It is important to avoid tobacco smoke exposure to reduce these health risks.
What causes mutations?
sunlight, radiation, and smoking
What increases genetic drift?
Mutations. Exposure to radiation, certain chemicals, and viral infections all increase mutation rates.
What is radiation exposure safety?
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
What alternative treatments are available to radiation over exposure?
There is considerable interest these days in benevolent chemicals called "free radical scavengers."
What is chromosomal imbalance?
Chromosomal imbalance refers to an abnormality in the number or structure of chromosomes in an individual's cells. This can be due to errors during cell division, exposure to certain chemicals or radiation, or genetic conditions. Chromosomal imbalances can lead to various health issues and developmental disorders.
How is mouth cancer caused by cigerettes?
Chemicals (carcinogens) in the smoke, and the heat irritate the tissues of the mouth. Long term exposure to tobacco damages the cells, causing uncontrolled growth of abnormal cells.
Explain how radiation can cause cancer?
Radiation can cause cancer by damaging the DNA in cells. This damage can lead to mutations that disrupt the normal cell growth and division, potentially resulting in uncontrolled cell growth - which is the hallmark of cancer. Long-term exposure to radiation, such as from X-rays or gamma rays, can increase the risk of developing cancer.
Which accurately describes the relationship between cancer risk and exposure to mutagens?
The relationship between cancer risk and exposure to mutagens is generally positive, as mutagens can cause changes in the DNA that lead to mutations, which are a key factor in cancer development. Increased exposure to mutagens, such as certain chemicals, radiation, or infectious agents, elevates the likelihood of acquiring mutations that may disrupt normal cell function and promote uncontrolled cell growth. Consequently, understanding and minimizing exposure to known mutagens is crucial in cancer prevention strategies.
