  • Chemical synaptic transmission is primarily through the release of neurotransmitters from presynaptic neural cells to postsynaptic receptors.

If there are 8 chromosomes in the parent cell, after Mitosis, how many chromosomes will be in the 2 daughter cells created?
leonid [27]

Answer:

8 chromosomes in each daughter cell

Explanation:

Mitosis creates identical cells. If there are 8 chromosomes in the parent cell, there will be 8 chromosomes in each daughter cell. The way it works is that in late Interphase, the number of chromosomes and DNA double. In this case there would be 16 chromosomes. And when the cell splits into two during cytokinesis, each of the two would get half the chromosomes. Hence, there would be 8 chromosomes in each daughter cell.
