Answer:

during the telophase stage

Explanation:

<em>The chromosomes decondense back to strands of chromatin and each set of separated genetic material becomes enclosed in a nuclear envelope to form two daughter nuclei </em><em>at the telophase stage of the cell cycle.</em>

Mitotic cell cycle is divide into the interphase during which the cell prepares for active division and the m phase during which the cell enters active division.

The active division (mitosis) has 4 main stages:

  • <em>prophase</em>
  • <em>metaphase</em>
  • <em>anaphase</em>
  • <em>telophase</em>

At the prophase, the cell membrane disolves and the chromossomal materials condense to become visible as chromosomes. Spindle formation becomes initiated at the same time.

At the metaphase, the chromosome aligns at the center of the cell to form the metaphase plate with each chromosome being engaged at the centromere by the spindle from the opposite poles of the cell.

Chromosome separates into sister chromatids at anaphase and commence their migration to opposite ends of the cell as a result of shortening of the spingle fiber at the anaphase.

The telophase is characterised by completed migration and decondensation of chromosomes and the reappearance of the nuclear envelope around each group of separated genetic materials to form two daughter nuclei.

<u>The cytoplasm eventually divides to form two daughter cells during cytokinesis.</u>

Answer:telophase

Explanation: cell division occurs for the reproduction of cells.the daughter cells formed bears the genetic characteristic of the parent cell. It may be meiosis or mitosis.

In meiosis, four daughter cells are formed,each with half the number of chromosomes as the parent cell.in mitosis,two daughter cells are formed ,each with the same number of chromosomes as the parent cell.

Cell division usually involves Prophase, metaphase, anaphase and telophase.

In Prophase,the chromosomes shorten and thicken.the nucelolus disappears and the nuclear membrane opens up.

In metaphase,the chromosomes migrate and attach to the spindle fibres.in anaphase,the spindle shorten and the chromatids belonging to each chromosomes separate from each other to the individual poles of the cell.

In telophase,the chromatids reach the poles of the cell.the spindle fibres breaks down.the nuclear membrane is formed,the nucleolus is formed.the chromosomes uncoils to their normal form. Then cytokinesis occurs to divide the cytoplasm to two daughter cells

What does the shape of a protein molecule determine
dalvyx [7]

The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
