Mutations can arise from the following:
Substitution- one base is inserted for another.
Deletion- a base is removed, which causes a frame shift drastically changing the codon sequence.
Insertion- a base is added to the sequence, which also causes a frame shift.
Translocation-group of bases are moved some place else in the genome. This results with altered function.
Tansposable elements- genes move from one location in the genome to another. This may happen in coding or non-coding regions.
Inversion- a segment of chromosome is reversed in its orientation and has significant effect on gene expression

Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What is spontaneous and induced mutations?
Spontaneous mutations occur naturally due to errors in DNA replication, exposure to mutagens, or changes in cellular processes. Induced mutations are deliberately caused by exposure to external factors such as radiation, chemicals, or certain drugs to study the effects of specific genetic changes.
Spontaneous changes in genetic material are called?
Spontaneous changes in genetic material are called mutations. These changes can occur naturally during DNA replication or as a result of environmental factors such as radiation or chemicals. Mutations can affect an organism's traits and may contribute to genetic diversity in a population.
What mutations occur during cell division?
During cell division, mutations can occur due to errors in DNA replication, exposure to mutagens (such as chemicals or radiation), or spontaneous molecular changes. These mutations can lead to changes in the genetic information of the daughter cells, potentially causing genetic disorders or contributing to the development of cancer.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What is spontaneous and induced mutations?
Spontaneous mutations occur naturally due to errors in DNA replication, exposure to mutagens, or changes in cellular processes. Induced mutations are deliberately caused by exposure to external factors such as radiation, chemicals, or certain drugs to study the effects of specific genetic changes.
What is spontaneous mutations?
in the nucleus
What do we call mutation that is brought about by the earth natural radioactivity?
Natural radioactivity can cause spontaneous mutations in an organism's DNA. These mutations are often referred to as spontaneous mutations or radiation-induced mutations.
Spontaneous changes in genetic material are called?
Spontaneous changes in genetic material are called mutations. These changes can occur naturally during DNA replication or as a result of environmental factors such as radiation or chemicals. Mutations can affect an organism's traits and may contribute to genetic diversity in a population.
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 in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
What causes mutations?
sunlight, radiation, and smoking
What is one way that changes can occur in a DNA sequence?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
What mutations occur during cell division?
During cell division, mutations can occur due to errors in DNA replication, exposure to mutagens (such as chemicals or radiation), or spontaneous molecular changes. These mutations can lead to changes in the genetic information of the daughter cells, potentially causing genetic disorders or contributing to the development of cancer.
What conditions must be met for a spontaneous process to occur?
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
