Can gene mutation occur in both mitosis and meiosis?

There are many different kinds of mutations. Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population.

What occurs in both mitosis and meiosis?

Which of the following occur in both mitosis and meiosis? Explanation: The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis. Prophase II and metaphase II only occur in meiosis, as does recombination between homologous chromosomes.

Is mitosis and meiosis genetically the same?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

What mutation occurs during meiosis?

When homologous chromosomes misalign during meiosis, unequal crossing-over occurs. The result is the deletion of a DNA sequence in one chromosome, and the insertion of a DNA sequence in the other chromosome.

Can meiosis and mitosis occur in the same organism?

Yes, they can occur. Mitosis is essentially a duplication process: It produces two genetically identical “daughter” cells from a single “parent” cell, whereas, Meiosis, on the other hand, shuffles the genetic deck, generating daughter cells that are distinct from one another and from the original parent cell.

Do both mitosis and meiosis require DNA replication?

Yes, DNA replicates in both mitosis and meiosis. In meiosis, the cell undergoes two divisions, i.e. meiosis I and II. Meiosis I is reduction division and meiosis II is similar to mitosis but DNA replicates only once during meiosis, i.e. before meiosis I in S phase.

How are the processes of mitosis and meiosis both alike and different?

Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase. … The resulting offspring is genetically different in the case of meiosis, while the offspring is identical in the case of mitosis.

Which of the following is true about both mitosis and meiosis?

In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.

Which stage in the cell cycle occurs only once in both mitosis and meiosis?

A cell cycle containing interphase followed by meiosis happens only once. Why? Mitosis produces new body cells that have all the chromosomes of the original cell and thus can be replicated over and over again to produce additional cells, all of which will be genetically identical.

How does DNA replication differ between mitosis and meiosis quizlet?

How does DNA replication differ between mitosis and meiosis? a. DNA replication takes less time in meiosis because the cells are haploid.

How do gene mutations occur?

Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.

Which occurs in meiosis but not in mitosis?

The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Which type of reproduction occurs by mitosis?

Asexual reproduction uses the process of mitosis to create the identical copies (clones) of the parent cell. It therefore leads to offspring that show no genetic variation.

How mutated genes are passed to daughter cells during mitosis?

During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two “daughter” cells that inherit the same genetic information. This process is called chromosome segregation.

Why do organisms need both mitosis and meiosis?

Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.
