What is the difference between prophase and telophase?
Telophase is the last stage of mitosis, whereas prophase is the starting stage of mitosis. During telophase, chromosomes loosen up whereas condensation begins in prophase. In telophase, a nuclear membrane forms around each set of chromosomes at the pole whereas, in prophase, the nuclear membrane begins to dissolve.
How do telophase I and telophase II differ during meiosis?
How do telophase I and telophase II differ during meiosis in animal cells? Cells remain diploid at the end of telophase I, but are haploid at the end of telophase II. Daughter cells form a cell plate to divide during telophase I, but divide by cytokinesis during telophase II.
How is telophase in mitosis different than telophase II?
The difference between telophase I in meiosis and telophase during mitosis is the that found near each post of the axle is a haploid arrangement of chromosomes. Limited uncoiling occurs before the chromosomes move onto the second cell division stage in meiosis (telophase II)
What is the difference between prophase 1 and 2?
The main difference between prophase 1 and 2 is that genetic recombination occurs through crossing overs and the “Chiasmata” formation during prophase 1 whereas no genetic recombination is noticed at the prophase 2.
How is prophase of meiosis and prophase of mitosis similar?
Prophase, in both mitosis and meiosis, is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome. This organelle controls the microtubules in the cell, and each centriole is one half of the organelle. During prophase, they separate to provide microtubule centers in each new cell.
How is prophase I different from prophase II in meiosis?
The key difference between prophase I and prophase II is that the prophase I is the beginning phase of meiosis I, and there is a long interphase before it while the prophase II is the first phase of meiosis II without an interphase prior to it.
Which of the following distinguishes prophase I of meiosis I from prophase of mitosis?
Solution
| Prophase-I of Meiosis | Prophase of Mitosis |
|---|---|
| Prophase I | |
| Chromosomes appear double from the very start | Prophase chromosomes do not look double in the beginning |
| Homologous Chromosomes pair and often undergo crossing over in prophase-I | There is no pairing of homologous chromosomes, hence no chance of crossing over |
What is the difference between prophase 1 and prophase 2?
What is the stage between telophase 1 and prophase 2?
Telophase 1 is followed by prophase 2. No interphase can be found between telophase 1 and prophase 2. During meiosis 2, individual bivalent chromosomes are divided into sister chromatids, ultimately known as daughter chromosomes. Meiosis 2 produces haploid gametes from diploid cells which result in meiosis 1.
What happens in prophase 1 and 2 of meiosis?
Prophase I The first is the condensation of chromatin into chromosomes that can be seen through the microscope; the second is the synapsis or physical contact between homologous chromosomes; and the crossing over of genetic material between these synapsed chromosomes.
What are the differences between meiosis 1 and meiosis 2?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. 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 main difference between prophase 1 in meiosis and prophase in mitosis?
Chromosomes condense and the centrosomes begin to form an early spindle. Meiotic prophase I is much longer that mitotic prophase. During prophase I homologous chromosomes make contacts with each other called chiasmata and “crossing over” occurs. This is where chromosomes exchange sections of DNA.
