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.
How do mutations happen in nature?
Mutations can happen spontaneously when DNA is replicated incorrectly during cell division or from exposure to environmental factors like radiation or chemicals. These changes can alter the genetic code, leading to new traits that may be beneficial, harmful, or have no effect on an organism's survival.
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 is radiation exposure safety?
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
What increases genetic drift?
Mutations. Exposure to radiation, certain chemicals, and viral infections all increase mutation rates.
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.
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 can cause a mutation when the cell copies its DNA?
Mutations can be caused by errors during DNA replication, exposure to mutagens (such as UV radiation or chemicals), or spontaneous changes in the DNA sequence. These changes can alter the genetic information carried by the DNA, potentially leading to genetic variations or diseases.
