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 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 is the change of DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals?
A mistake in DNA replication or exposure to radiation or chemicals can lead to changes in the DNA sequence known as mutations. Mutations can cause changes in the genetic information carried by the DNA, which can potentially result in alterations to the structure or function of the proteins that are encoded by the affected genes. These changes can have various effects, from no impact to potentially leading to diseases such as cancer.
What causes mutations?
sunlight, radiation, and smoking
What kinds of factors can cause a prophage to become virulent?
Factors such as UV light exposure, certain chemicals or drugs, stress to the host cell, or changes in environmental conditions can trigger a prophage to become virulent by inducing the lytic cycle and leading to the production of viral particles. These triggers can disrupt the lysogenic cycle and activate the lytic genes within the prophage.
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 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.
What alternative treatments are available to radiation over exposure?
There is considerable interest these days in benevolent chemicals called "free radical scavengers."
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.
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.
What are carcinogens and what can cause them?
Carcinogens are cancer-causing things, including some chemicals and some types of radiation. The risk for their causing cancer can be brought about by smoking, by exposure to ultraviolet radiation, nuclear radiation, or to a wide range of toxic substances.
