Answer:
Metaphase
Explanation:
The M phase of the cell cycle is the phase during which the nuclear content and cellular content is distributed. The distribution of the nuclear content takes place in four phases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes are aligned at the equatorial plate during the metaphase after which the chromosomes separate. The phase during which the separation of the chromosomes takes place is known as anaphase so the phase before the anaphase is the phase during which the chromatids are not separated that is the metaphase.
Thus, metaphase is the correct answer.
In mitosis, the last phase where chromatids are together is the metaphase. After this, during the anaphase, sister chromatids separate and move towards opposite poles.
In mitosis, the last phase where chromatids are together is the metaphase. During this stage, chromosomes line up across the centre of the cell and each chromosome is connected to a spindle fibre at its centromere. This ensures equal division of chromosomes into each of the two new cells. After the metaphase, during anaphase, the centromeres of each chromosome separate and the sister chromatids move away from each other towards opposite poles.
