Instruction: Answer the following questions. 1. A mosquito cell in interphase has six chromosomes. How many sister chromatids does the same cell have during metaphase? Explain.
Answer (1)
During interphase, a mosquito cell has six chromosomes, each consisting of a single chromatid. However, during metaphase, DNA replication has already occurred. This means each chromosome has duplicated, resulting in two identical sister chromatids joined at the centromere. Therefore, a mosquito cell in metaphase with six chromosomes will have a total of twelve sister chromatids (six chromosomes x two sister chromatids/chromosome).
