Verified step by step guidance

Understand the structure of chromosomes and chromatids: A chromosome consists of two sister chromatids joined at the centromere. During cell division, the number of chromatids doubles as each chromosome is replicated.

Review the phases of mitosis: Mitosis consists of several phases - prophase, metaphase, anaphase, and telophase. Each phase has distinct characteristics and changes in chromosome structure.

Focus on metaphase: During metaphase, chromosomes align at the cell's equatorial plane. At this point, each chromosome consists of two sister chromatids, effectively doubling the number of chromatids compared to the original number of chromosomes.

Compare chromatids in metaphase to the original cell: In the original cell, chromosomes are single structures. In metaphase, each chromosome is replicated into two chromatids, thus doubling the chromatids.

Conclude with the identification of the phase: Based on the doubling of chromatids, identify metaphase as the phase where chromatids are twice the number of the original chromosomes.
