Answer options:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
b.) chromosomes are divided evenly during cell division so that each new daughter cell has an equal share of the original set.
c.) chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.
d.) chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.
Answer:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
Explanation:
The cell divisions that allow organisms to grow are called mitosis. Before mitosis, all the DNA is duplicated.
Then, during mitosis, it condenses to form chromosomes. The identical chromosomes align in the centre of the cell. Then, they are equally distributed to among two daughter cells.
These two daughter cells each have a complete set of chromosomes. Each daughter cell identical to the parent cell and to the other daughter cell.
