16. Cell Division
Mitosis
Multiple Choice
In cell division, both mitosis and meiosis are processes that:
A
Segregate duplicated chromosomes into daughter nuclei after DNA replication
B
Produce genetically identical daughter cells in every division
C
Reduce the chromosome number by half in a single division
D
Occur only in prokaryotic cells during binary fission
Verified step by step guidance1
Understand the context: Both mitosis and meiosis are types of cell division that occur in eukaryotic cells, not prokaryotic cells. So, eliminate options related to prokaryotic cells and binary fission.
Recall the purpose of mitosis: Mitosis results in two genetically identical daughter cells, maintaining the chromosome number. It segregates duplicated chromosomes into daughter nuclei after DNA replication.
Recall the purpose of meiosis: Meiosis reduces the chromosome number by half through two rounds of division, producing genetically diverse gametes.
Identify the common feature: Both mitosis and meiosis involve segregation of duplicated chromosomes into daughter nuclei after DNA replication, which is a fundamental step in both processes.
Conclude that the correct answer is the option stating that both processes segregate duplicated chromosomes into daughter nuclei after DNA replication, as this applies to both mitosis and meiosis.
