WebApr 10, 2024 · In this phase of prophase, I, singular chromosomes—each comprising two sister chromatids—progress toward becoming "individualized" to shape strands inside the nucleus. The two sister chromatids closely associate and are outwardly distinct from each other. During leptotene, horizontal components of the synaptonemal complex gather. WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis.
