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 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 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 process can Genetic changes in mitosis can only occur by?
Genetic changes in mitosis can only occur through mutations, which are changes in the DNA sequence. These mutations can be caused by errors during DNA replication, exposure to mutagens like radiation or chemicals, or spontaneous changes in the DNA.
Mutations that affect a single gene occur during?
Mutations that affect a single gene can occur during DNA replication, exposure to mutagenic agents like chemicals or radiation, or errors during repair processes. These mutations can result in changes to the DNA sequence of the gene, which can then impact the function of the protein it encodes.

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 causes mutations during the process of protein synthesis?
Mutations during protein synthesis can be caused by errors in DNA replication, exposure to mutagens like radiation or chemicals, or spontaneous changes in the genetic code. These mutations can alter the sequence of amino acids in a protein, potentially affecting its structure and function.
Mutations that affect a single gene occur during?
Mutations that affect a single gene can occur during DNA replication, exposure to mutagenic agents like chemicals or radiation, or errors during repair processes. These mutations can result in changes to the DNA sequence of the gene, which can then impact the function of the protein it encodes.
What is the permanent change in the sequence of DNA in a gene called?
A permanent change in the sequence of DNA in a gene is called a mutation. Mutations can result from errors in DNA replication, exposure to environmental factors like radiation or chemicals, or as a result of genetic inheritance. These changes can alter the function of the gene and potentially lead to genetic disorders or diseases.
Any alteration of the DNA sequence is a?
mutation. Mutations can be caused by various factors such as exposure to radiation, chemicals, or errors in the DNA replication process. Mutations can have different effects on an organism, ranging from no discernible impact to causing genetic disorders or diseases.
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.
How does a mutation occur?
A mutation is a change in the DNA sequence that can arise spontaneously during cell division, due to errors in DNA replication or exposure to environmental factors like radiation or chemicals. Mutations can also be inherited from parents and can occur in different ways, such as single nucleotide changes, insertions, deletions, or rearrangements of DNA segments.
How are substitution mutations caused?
Substitution mutations are typically caused by errors during DNA replication, where a wrong nucleotide is incorporated into the DNA sequence. This can also be caused by exposure to mutagens, such as certain chemicals or radiation, which can lead to changes in the DNA nucleotide sequence.
