NEET BIOLOGY

Detailed explanation-1: -Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Detailed explanation-2: -Prophase-the first stage of mitosis. Spindles attached to kinetochores begin to shorten. This exerts a force on the sister chromatids that pulls them apart. Spindle fibers continue to shorten, pulling chromatids to opposite poles.

Detailed explanation-3: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Detailed explanation-4: -Prophase I is divided into five phases: leptotene, zygotene, pachytene, diplotene, and diakinesis.

Detailed explanation-5: -1 Prophase. Prophase begins as the chromatin starts to condense from its metabolically active state into well-defined chromosomes that are more easily moved through the cytoplasm. Each chromosome is composed of two sister chromatids.
