Verified step by step guidance

Understand the context of mitosis: Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

Recall the definition of sister chromatids: Sister chromatids are two identical copies of a single chromosome that are connected by a centromere after DNA replication.

Identify the role of sister chromatids during mitosis: During mitosis, sister chromatids are separated into two new nuclei, ensuring each daughter cell receives an identical set of chromosomes.

Differentiate sister chromatids from homologous chromosomes: Homologous chromosomes are pairs of chromosomes (one from each parent) that pair during meiosis, not mitosis.

Recognize that crossing over and chromosome separation during meiosis I involve homologous chromosomes, not sister chromatids, which are specific to mitosis.
