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.
Which of the following can cause a mutation in a gene?
An error in the repair of damaged DNA-Apex
Why does exposure to uv radiation cause death in vegetative cells but not endospores?
UV radiation causes damage to the DNA of vegetative cells, leading to cell death. Endospores, on the other hand, have a protective protein layer that shields their DNA from UV radiation damage, allowing them to survive exposure. This difference in DNA protection is why endospores are more resistant to UV radiation compared to vegetative cells.
How can nuclear radiation effect living organisms?
Nuclear radiation can damage cells in living organisms, leading to DNA mutations, cell death, and tissue damage. It can cause acute radiation sickness or lead to long-term health effects such as an increased risk of cancer or genetic mutations in future generations. The extent of the impact depends on the dose, duration of exposure, and type of radiation.
What can cause changes in DNA sequences?
mutations
What are the risks of nuclear radiation?
The exposure to nuclear radiation has many risks associated with it. Cancer, DNA mutations, and radiation poisoning can all occur with any level of radiation exposure.
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 can cause mutation when the cell copies its DNA?
i seriously dont know.. in error, exposure to chemicals and exposure to radiation
What are the best ways to protect against the effect of exposure?
Radiation
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.
Why is nuclear radiation dangerous and what are the potential risks associated with exposure to it?
Nuclear radiation is dangerous because it can damage cells and DNA in the body, leading to health problems like cancer, radiation sickness, and genetic mutations. Exposure to nuclear radiation can increase the risk of developing these health issues, depending on the level and duration of exposure. It is important to limit exposure to nuclear radiation to protect against these potential risks.

Does radiation mutate the body?
Radiation can damage DNA in cells, potentially leading to mutations and increasing the risk of cancer. However, the extent of mutations and their impact on the body depend on the dose, type of radiation, and duration of exposure. Protection and precautions can minimize the risks associated with radiation exposure.
Why does exposure to uv radiation cause death in vegetative cells but not endospores?
UV radiation causes damage to the DNA of vegetative cells, leading to cell death. Endospores, on the other hand, have a protective protein layer that shields their DNA from UV radiation damage, allowing them to survive exposure. This difference in DNA protection is why endospores are more resistant to UV radiation compared to vegetative cells.
Are animals not affected by radiation?
Animals can be affected by radiation exposure, just like humans. Their sensitivity to radiation depends on factors such as the type of radiation, dose, duration of exposure, and species of the animal. High levels of radiation can cause DNA damage, mutations, and other health issues in animals.
What part of the cell is particularly at risk from exposure to ultra-violet rays?
The cell's DNA is particularly at risk from exposure to ultra-violet rays. UV radiation can cause damage to the DNA structure, leading to mutations and potential cell death. Cells have mechanisms to repair this damage, but excessive exposure can overwhelm these repair processes.
