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 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.
What potential consequences or benefits can occur when crossing over results in a genetic exchange between homologous chromosomes during meiosis?
When crossing over occurs during meiosis, it can lead to genetic diversity among offspring. This can result in benefits such as increased adaptability to changing environments and improved chances of survival. However, it can also lead to potential consequences such as the introduction of harmful mutations or genetic disorders.
New inherited characteristics may appear in offspring as a result of new combinations of existing genes or may result from mutations in genes comtained in cells produced by structure?
That's correct! New inherited characteristics in offspring can result from new combinations of existing genes during meiosis, leading to genetic variation. Mutations in genes can also occur, creating new genetic traits that can be passed down to future generations.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
Can mutation be passed along to human offspring through meiosis and mitosis?
Yes, mutations can be passed along to human offspring through both meiosis and mitosis. Mutations that occur in the germ cells during meiosis can be passed on to offspring, while mutations that occur in somatic cells during mitosis can potentially lead to a mosaic pattern of mutated and normal cells in an individual.
During meiosis how many replications occur?
DNA replicates once during meiosis. This is why the end result is four haploid cells.

Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
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.
If a child is born with down syndrome when did the mutation occur?
During meiosis
What happens in meiosis that does not occur in meiosis?
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.
What happens in meiosis you that does not occur in meiosis?
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
