Question

complex organisms must contain numerous cells to exist. these cells are constantly dividing through cell two daughter cells produced during mitosis?
the dna from the parent cell does not share any dna with the two daughter cells.
the dna from the parent cell is 50% identical to the dna in the two daughter cells.
the dna from the parent cell is 75% identical to the dna in the two daughter cells.
the dna from the parent cell is 100% identical to the dna in the two daughter cells.

Explanation:

Mitosis is a cell division process where the parent cell's DNA is replicated and then equally distributed to the two daughter cells. This results in the daughter cells having the same genetic material (DNA) as the parent cell, meaning the DNA from the parent cell is 100% identical to the DNA in the two daughter cells produced during mitosis. The other options are incorrect: the first option is wrong because daughter cells inherit DNA from the parent; the 50% and 75% options are incorrect as mitosis produces genetically identical daughter cells (in terms of DNA content and sequence, barring rare mutations).

Answer:

The DNA from the parent cell is 100% identical to the DNA in the two daughter cells.
