What mutations occur during cell division?
mutation is change and it doesnt happen during division. You must have got confused
Mutations in DNA often occur during replication. During which phase of the cell cycle do such mutations occur?
Genetic mutations occur during the S phase of the cell cycle (during interphase before mitosis or meiosis begins). This is when DNA is replicated, so any error would cause a mutation in the genetic code. Chromosomal nondisjunction is the failure of replicated chromosomes to separate, which causes extra or missing chromosomes in the daughter cells. This mutation can occur during meiosis I or II and during mitosis.
When does point mutation occur?
Bacic Answer:Point mutations occur when a single nucleotode is replaced with another nucleotide tide base. Insertion and come in this category.More Detail Answer:Point mutations occur when a single nucleotide is replaced with another nucleotide tide base. Insertion and come in this category. Error in the process of replication of DNA molecule results in point mutations. Sometimes heat of high level radiation cause the error in DNA replication. There are different effects of point mutations. if this type of mutation occurs in the sequence of DNA molecule or exon, then the protein sequence changes present in the gene. If the mutation occurs in the RNA effecting the codon of gene Sickle cell anemia is cause by the point mutations. Changes occur in the beta hemoglobin. it converts GAC sequence into GUG, Point mutation can be subdivided into three types:1) Nonsense mutations are the ones which code for the same amino acid.2) Misssense mutations occur in the genes which code for different amino acid.3)Silent mutations do not affect the function of the protein and code for different of same amino acid.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
Which of these statements represents a common misconception regarding point mutations?
mutations increase variety in a population. (apex)
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
Are mutations in the DNA sequence gene transient changes?
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
Mutations occur because of?
errors in DNA replication
How does mutations occur during DNA replication and transcription?
RNA polymerase doesn't have a proofreading function.
Although genetic mutations may occur spontaneously in organisms the incidence of such mutations may be increased by?
Radioactive substances in the environment

How do individuals acquire mutations?
Mutations are caused by radiation, viruses,transposons and mutagenic chemicals, as well as errors that occur during meiosis or DNA replication. They can also be induced by the organism itself, by cellular processes such as hypermutation.
How can and organism produced by asexual reproduction be unique and different from its parent?
A organism can be unique and different from its parent when mutation occurs during DNA replication.
Mutation in DNA often occurs during replication. during which phase of the cell cycle do such mutations occur?
The semiconservative replication of DNA occurs in the S phase or interphase of cell cycle. Mutation too occurs during this phase, whereas growth takes place in G phase.
