The two phases of mitosis that are essentially opposite in terms of changes in the nucleus are prophase (the first stage) and telophase (the last…
How are prophase and telophase opposites?
In prophase, the chromatin network begins to coil and appears as a long thread-like structures called chromosomes. … In telophase opposite poles of the chromosomes lose their identity and nuclear membranes is formed around the daughter nuclei. Nucleolus also reappears. So, it is reverse of prophase.
What is the opposite of telophase in mitosis?
Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage.
What is opposite of 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 phase of mitosis is in essence opposite to prophase?
Telophase stage of mitosis is essentially the reverse of prophase in terms of nuclear changes.
Which of the following does not occur during mitosis?
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.
What happens in the 4 stages of mitosis?
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …
What are differences between mitosis and meiosis?
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 are the major differences between mitosis and meiosis?
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
What is a distinguishing visible feature of each stage of mitosis?
Terms in this set (23) What is a key distinguishing visible feature of each stage of mitosis? telophase – two nuclei visible, cell splits. Once active cell division ends, the cells will enter interphase.
What is the opposite of prophase and Prometaphase?
Telophase is essentially the opposite of prophase and prometaphase. The chromosomes begin to unwind back into chromatin in preparation to direct the cell’s metabolic activities. A new nucleus forms around each set of chromosomes.
