Chromosomes align along midline of cell
WebThe process of chromosome congression and alignment is at the core of mitotic fidelity. In this review, we discuss distinct spatial routes that the chromosomes take to align during prometaphase, which are characterized by distinct biomolecular requirements. Peripheral polar chromosomes are an intriguing case as their alignment depends on the activity of … WebChromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase. Anaphase During anaphase, sister chromatids separate and the centromeres divide. The sister chromatids …

WebFeb 2, 2024 · The first step of cell division is prophase, during which the nucleus dissolves and the chromosomes begin migration to the midline of the cell. (Some biology textbooks insert a phase called "prometaphase" … WebChromosomes become visible in the cell Correct answer: Sister chromatids are separated Explanation: Prophase is the first stage of mitosis, during which the cell begins to position itself in order to separate the chromatids and divide. During prophase, the nuclear envelope and nucleolus are dissolved and the chromosomes condense.
