Scelta multipla
In a eukaryotic cell, what is the primary goal of mitosis?
A
To replicate DNA so that each chromosome is duplicated
B
To produce two genetically identical daughter cells by equally segregating duplicated chromosomes into two nuclei
C
To exchange segments of homologous chromosomes to increase genetic variation
D
To reduce the chromosome number by half to create haploid gametes

Understand that mitosis is a process of cell division in eukaryotic cells that ensures genetic material is accurately distributed.
Recognize that before mitosis begins, DNA replication occurs during the S phase of the cell cycle, so chromosomes are already duplicated.
Identify that the main purpose of mitosis is to separate these duplicated chromosomes equally into two new nuclei.
Note that this results in two daughter cells that are genetically identical to the original parent cell, maintaining the same chromosome number.
Distinguish mitosis from other processes like meiosis, which reduces chromosome number and increases genetic variation, unlike mitosis.
