In the cells of many eukaryotic species, the nuclear envelope has to disappear to permit which of the following events in the cell cycle? a) dna synthesis b) attachment of microtubules to kinetochores c) separation of the centrosomes d) condensation of the chromosomes

The cells of many eukaryotic species, the nuclear envelope has to disappear to permit the ''attachment of microtubules to the kinetochore''

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.

the answer is b.) hydrogen bonds between bases.
