The correct sequence of events during mitosis would be as follows (i) Condensation of DNA so that chromosomes become visible occurs during early to mid-prophase. (ii) Nuclear membrane disassembly begins at late prophase or transition to metaphase. (iii) Arrangement of chromosomes at equator occurs during metaphase, called congression.
Full Answer
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in this strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase.
The correct order of events in the cell cycle is G1, then S, then G2, then M with an optional exit to G0.
The CORRECT sequence of steps in the eukaryotic cell cycle is: G1 → S phase → G2 → mitosis → cytokinesis.
Stages of the cell cycle: interphase, mitosis, cytokinesis, g1 phase, g2 phase, synthesis phase, prophase, metaphase, anaphase, telophase.
Telophase —the final stage of mitosis when the chromosomes arrive at their respective poles. Vesicles reassemble into a new nuclear membrane surrounding the DNA of each daughter cell. At the end of telophase, the cell has two distinct nuclei and mitosis is complete.
The mitotic spindle helps align the sister chromatids correctly for proper cell division, ensuring each daughter cell gets one copy. Prometaphase —the second phase of mitosis, in which the nuclear membrane breaks down and spindle fibers attach to the centromere (region of a chromosome where microtubules of the spindles attach).
Interphase comprises the G 1, S, and G 2 phases, in which the cell grows and replicates its genetic material. The M phase consists of mitosis (subdivided into prophase, metaphase, anaphase, and telophase), in which the cell divides, producing two new, identical cells after undergoing cytokinesis.
The process of cell division that results in two cells that are genetic clones of the parent cell is called mitosis and occurs in most types of cells. The resulting daughter cells are diploid, which is the genetic state of a cell containing ...
The resulting daughter cells are diploid, which is the genetic state of a cell containing the full complement of chromosomes from its parent cells ( 2n ). In sexually reproducing organisms, like humans, a different process, called meiosis, creates the sex cells (eggs and sperm). In meiosis, the cells resulting from division contain only half ...
The spindle fibers tug the chromosomes back and forth as they position them correctly for the next stage. Metaphase —the third stage of mitosis, in which the sister chromatids line up along the cell equator. The chromosomes no longer move back and forth but stay aligned along the equator.
Mitosis. The cell cycle is the span of a cell from one division to another. Mitosis is the process of cell division to produce two daughter cells from one, with DNA being synthesized and each daughter cell receiving a copy. Cell division is the process by which one cell becomes two new cells.
Homologous chromosomes cross over during prophase I; during metaphase I, chromosomes align randomly. what is the major difference between and dominant and recessive alleles of the same traits. When both are present in the heterozygote, only the dominant allele is expressed.
During ------, the cell carries put its normal functions and the chromosomes are thinly spread out throughout the nucleus. interphase. locking through a light microscope at a dividing cell, you see two separate groups of chromosomes on opposite ends of the cell.
