During which phase(s) of mitosis are structure like the one shown in figure visible:
Correct answer: A. Prophase and metaphase
- A. Prophase and metaphase
- B. Anaphase and interphase
- C. Anaphase and prophase
- D. Prophase and telophase
Explanation
Chromosomes are visible during prophase and metaphase due to condensation. In prophase, chromatin condenses into distinct, visible chromosomes as they coil tightly. During metaphase, chromosomes align along the metaphase plate in the center of the cell, making them particularly visible under a microscope due to their condensed and highly organized structure. This condensation facilitates accurate segregation of genetic material during cell division.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
