Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.
Which of the following occurs during mitosis but not meiosis 1?
In mitosis, the sister chromatids of each double-stranded chromosome are separated through depolymerization of spindle fibers during anaphase. This does not occur during meiosis I but will occur in anaphase II of the second round of meiosis.
Which of the following happens in mitosis but not in meiosis?
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.
What is the difference between meiosis 1 and mitosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Which of the following occurs only in meiosis I but not in meiosis II?
Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
What is the occurs during mitosis?
What happens during mitosis? During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
What process occurs in both mitosis and meiosis?
Aside from these two distinct purposes, both mitosis and meiosis occur in multiple stages during which the same general things happen: DNA replication and condensation, nuclear membrane degradation, spindle formation, chromosomal segregation and nuclear reformation.
Where does mitosis occur in the body?
Mitosis is an active process that occurs in the bone marrow and skin cells to replace cells that have reached the end of their lives. Mitosis occurs in eukaryotic cells. Although the term mitosis is frequently used to describe the entire process, cell division is not mitosis.
What is the purpose of mitosis and meiosis quizlet?
Purpose of Mitosis is cell growth, repair, and replacement of cells. The purpose of meiosis is creating haploid cells (gametes) that can join/fuse for sexual reproduction multicellular organisms.
What are the similarities and differences of mitosis and meiosis?
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.
What are 3 similarities and 3 differences between mitosis and meiosis?
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
