mitosis
A)A scientist looks into a microscope and sees that replicated chromosome pairs are lined up in the center of a cell. The scientist then sees the mitotic spindle from each side of the cell attach to a chromosome. Which mitotic phase is the scientist likely witnessing?(1 point) Responses anaphase anaphase metaphase metaphase telophase telophase prophase
The scientist is likely witnessing the metaphase phase of mitosis.
During metaphase, replicated chromosome pairs line up at the center of the cell, forming what is known as the metaphase plate. This alignment allows for proper segregation of genetic material into the daughter cells. At this stage, the mitotic spindles from opposite sides of the cell attach to each chromosome, preparing for the subsequent separation of sister chromatids during anaphase.
Therefore, the correct answer is metaphase.
