Question

During metaphase, chromosomes line up along the equator of the cell. The cell then moves into anaphase, with microtubules attaching to the _______ of each chromosome. ions centromeres chloroplasts

Answer 1

Answer:

Centromeres

Explanation:

Cell division is a universal process for all living cells. The cells must divide in order to replicate or multiply. Cell division involves two major phases viz: Interphase and the Mitotic phase. The interphase is a preparatory phase. It is the phase where the cell replicates its DNA and prepares generally for the Mitotic phase.

The Mitotic phase involves mitosis or karyokinensis (division of nucleus) and Cytokinesis (division of cytoplasm). The mitosis occurs in four steps namely: Prophase, Metaphase, Anaphase and Telophase.

In the Metaphase, as stated in the question, the sister chromatids (chromosomes) joined at the centromere are lined up at the center or equator of the cell known as Metaphase plate. Microtubules from each pole of the spindle then attaches to each centromere of the chromosomes in order to pull them apart towards opposite poles in ANAPHASE.

Answer 2

This indicates that the cell is not responding to the internal regulators inside the cell.
