Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
DNA replication and transcription occur in the what?
Nucleus.
What DNA begins to uncoil DNA?
DNA helix uncoils the DNA for transcription to occur.
Which of these statements represents a common misconception regarding point mutations?
mutations increase variety in a population. (apex)
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.
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
Can Mutations can spontaneously occur during DNA replication?
Yes
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
DNA replication and transcription occur in the what?
Nucleus.
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
What DNA begins to uncoil DNA?
DNA helix uncoils the DNA for transcription to occur.
What mutations occur during cell division?
mutation is change and it doesnt happen during division. You must have got confused
Which of these statements represents a common misconception regarding point mutations?
mutations increase variety in a population. (apex)
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.
Where in the cell do replication translation and transcription occur?
Most of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur.In eukaryotic cells, mitochondria and chloroplastsalso contain DNA, which performs replication and transcription inside these organelles.In prokaryotic cells there is no nucleus. The DNA is in a region of the cytoplasm called the nucleoid, and that is where DNA replication and transcription occur in these cells.
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.
