Cell Division: Easy Mitosis Notes for NEET Exam Preparation  Stages of Mitosis showing chromosome condensation, alignment, separation and formation of two daughter nuclei. -  Dr.Sanjaykumar Pawar  Metaphase (Mitosis) – Notes Metaphase is the second phase of mitosis. It starts after the nuclear envelope completely breaks down. Nuclear membrane disappears completely. So, chromosomes are now freely spread in the cytoplasm. Chromosomes are fully condensed. They become short, thick, and clearly visible under the microscope. This is the best stage to study chromosome shape and structure. Because chromosomes are most distinct at this time. Each chromosome consists of two identical sister chromatids. These chromatids are exact copies of each other. Both sister chromatids are joined at a point called the centromere. The centromere holds them together. At the centromere, disc-shaped structures called kinetochores are present. These act as attachment poi...

M PHASE (Mitosis) – Easy (NEET Level)   M Phase (Mitosis) mind map showing all stages and key NEET points in a simple visual tree format. - Dr.Sanjaykumar Pawar  M PHASE (Mitotic Phase) Text: This is the most dramatic period of the cell cycle, involving a major reorganisation of virtually all components of the cell. Easy Notes: M phase is the cell division phase . It is called the most dramatic phase because the whole cell changes. The nucleus, chromosomes, cytoplasm, and cell organelles are rearranged. The cell prepares to divide into two new daughter cells . 📝 NEET Point: Maximum visible changes occur in the M phase. Text: Since the number of chromosomes in the parent and progeny cells is the same, it is also called equational division. Easy Notes: Parent cell and daughter cells have the same number of chromosomes . No chromosome number is reduced. Therefore, mitosis is called Equational Division . 📝 NEET Point: Parent cell = 2n Daughter cel...
