Question

during what phase of mitosis do chromosomes condense to form visible structures under the microscope?

Answer 1

During prophase of mitosis, chromosomes condense to form visible structures under the microscope. In this phase, the chromatin fibers become tightly coiled and folded, making the chromosomes distinguishable as distinct entities. Each chromosome is composed of two sister chromatids joined at a region called the centromere. This condensation is crucial for ensuring accurate segregation of chromosomes during the later stages of mitosis.
