During this phase, chromosomes have condensed and appear thick and lumpy a.) interphase b.) anaphase c.)metaphase d.)prophase plz me

In prophase of cell cycle, chromosomes have condensed and appear thick and lumpy.

Further Explanation:

The cell cycle is referred as the prearranged flow of steps that include the cellular division as well as cell growth. This cycle form two new daughter cells. The cycle is begins with the interphase. In this phase, mainly the cell replicates and matures its DNA.

The second stage of a cell cycle is the mitosis or M phase. Mitosis is a kind of cell division. In this, parental cells divide into two daughter cells which have the same number of chromosomes as that of the parent cell.

This phase starts with:

Prophase: During this phase, the condensation of the chromosomes takes place and these chromosomes become visible. Spindle fibers are produced in this stage. Also, the nuclear envelope breakdown takes place.

Metaphase: In this stage, the formation of spindle fibers is done and centrosomes are established at the contrary terminals of the cell. The chromosomes line up at the metaphase plate. Each of the sister chromatids is linked to the spindle fiber starting from the opposite poles.

Anaphase: During this phase, the cohesion proteins link with the sister chromatids and split them down. The sister chromatid are pulled towards the opposite end of the cell and non-kinetochore spindle fibers get increase in length and elongate a cell.

Telophase: This is the end phase of the cell cycle. In this chromosomes are arrived at the opposite terminals and decondensation of chromosome occurs. The nuclear envelope and mitotic spindle fiber are break down.
