A diploid cell with 10 chromosomes undergoes DNA replication, forming 20 sister chromatids. Following mitosis, the cell divides into two daughter cells, each containing 10 chromosomes. Which of the following conclusions is best supported by these events?
The replication process transforms the 10 chromosomes into 20 completely separate chromosomes that are then randomly divided, so there is no expectation of equal partitioning.
Despite the duplication of genetic material in interphase, mitosis inherently results in a doubling of chromosome number in each daughter cell, contradicting the concept of equal distribution.
Proper mitosis ensures that the 20 sister chromatids segregate equally, thereby each daughter cell inherits 10 chromosomes, preserving the original chromosomal number.
Mitosis results in the unequal distribution of sister chromatids, often leading to one daughter cell with all 20 and the other with none, which is inconsistent with normal cell division.
