Arrange the main stages of mitotic cell division in eukaryotic cells in the correct chronological order from beginning to end:

  1. 1Prophase (Chromosomes condense and nuclear envelope breaks down)
  2. 2Metaphase (Chromosomes align along the equatorial plate of the cell)
  3. 3Anaphase (Sister chromatids separate and move toward opposite poles)
  4. 4Telophase (Nuclear envelopes re-form around separated chromosomes at opposite poles)

Cevap

The correct chronological order of mitosis stages is Prophase, followed by Metaphase, Anaphase, and Telophase.
Mitosis proceeds in four main sequential phases: Prophase (condensation of chromatin and disintegration of the nuclear membrane), Metaphase (alignment of chromosomes at the cell equator), Anaphase (separation of sister chromatids to opposite poles), and Telophase (re-formation of nuclear membranes around daughter nuclei).

Adım Adım Çözüm

1
Identify the initial phase of nuclear division.
Prophase is selected as the first stage.
Chromosomes must condense and the nuclear envelope disintegrates to allow spindle attachment.
2
Identify the phase of alignment.
Metaphase is selected as the second stage.
Spindle fibers align chromosomes along the metaphase plate.
3
Identify the phase of chromatid separation.
Anaphase is selected as the third stage.
Sister chromatids are pulled apart toward opposite poles of the cell.
4
Identify the final phase of nuclear reformation.
Telophase is selected as the fourth stage.
Decondensing chromosomes are enclosed by new nuclear membranes.
