Question

Explain the process of mitosis in a tissue culture for normal cells.

Answer 1

Answer:

Cell tissue is taken from a living organism.

Cells divide and reproduce in the culture.

Cells continue mitosis until they are touching, then they stop reproducing until a cell dies.

Cells reproduce one layer thick and then stop reproducing.

Cells undergo 20 to 50 mitotic divisions in a tissue culture.

Explanation:

Answer 2

Interphase-intermediate phase, DNA replicates

Prophase -coils into chromosomes, chromosomes are made of two chromatids, which join at the centromere at this stage.

Metaphase -Chromosomes line up in the middle of cell on spindles

Anaphase - Chromosomes are pulled apart to opposite ends of the cell by the spindles

Telophase - The cell splits into two cells, and the chromosomes uncoil and begin from the interphase stage again
