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.
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 is an environmental factor that could cause a base sequence in DNA to be changed to a different base sequence?
Exposure to ultraviolet (UV) radiation can cause DNA damage and lead to a base sequence change. UV radiation can induce thymine dimers, where two adjacent thymine bases bond together, leading to errors during DNA replication.
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.
A mutation is a change in DNA sequence and what?
A mutation is a change in the DNA sequence that can lead to alterations in the protein produced or affect the functioning of the gene. Mutations can arise spontaneously or be induced by external factors like radiation or chemicals. Some mutations can be harmful, while others may have no effect or even be beneficial.

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 happens when cells are exposed to nuclear radiation?
Exposure to nuclear radiation can damage cells by disrupting their DNA, leading to mutations and potential cell death. This damage can result in a variety of health effects, including increased risk of cancer, infertility, and radiation sickness. The severity of the impact depends on factors such as the dose of radiation received and the type of radiation.
What will happen to the process of cell division if cells are exposed to radiation?
It stops it because radiation causes the DNA to take on a conformation, or form, that cannot be replicated by polymerase.

When are mutations likely to occur?
Mutations can occur during DNA replication, cell division, or exposure to environmental factors like radiation or chemicals. They are more likely to occur in rapidly dividing cells, such as during development or in cancer cells.
Can you tamper with DNA?
Not directly. Radiation can cause mutations in DNA. Excess heat (as in the case of a fever) can denature (destroy) the DNA sequence as well as other proteins which will usually result in cell death.
How do radioisotopes identify DNA?
Radioisotopes are often used to label DNA molecules for detection purposes. This is achieved by incorporating radioactively labeled nucleotides during DNA replication or using radiolabeled probes that bind specifically to the DNA sequence of interest. By detecting the emitted radiation from the radioisotope, researchers can locate and identify the DNA molecules.
Which of the following determines the specificity of a DNA probe?
complementary base pairing-apex
