Respuesta :
The correct answer is B)attachment of microtubules to kinetochores.
Mitosis is a process of cell division in which newly replicated chromosomes separated equally into two parts of a cell. During late prophase of the mitotic cycle, the nuclear envelope breaks down or disappear. This allows attachment of the microtubules to the kinetochores of sister chromatids at the metaphase-anaphase transition. The attachment finally leads to the formation of two daughter cells.
The cells of many eukaryotic species, the nuclear envelope has to disappear to permit the ''attachment of microtubules to the kinetochore''
Answer: Option B
Explanation:
One of the most important and ideal Hallmark of cell division is the ''mitosis'' and ''meiosis'' , both of which requires the attachment of the microtubules of the cell to the kinetochore of the chromosome. These microtubules pull the chromosomes to the opposite poles thereby facilitating the splitting of the parent cells into 2 daughter cells.
