Chromosomes can be seen only during: A. active transport B. cell division c. meiosis D. neutralization
The correct answer is B. cell division.
To understand why chromosomes can be seen only during cell division, let's take a closer look at what chromosomes are and the different stages of the cell cycle.
Chromosomes are structures made up of DNA that carry genetic information. They are located in the nucleus of a cell and play a crucial role in cell growth, development, and reproduction. Chromosomes are not visible in their condensed form during the entire cell cycle.
The cell cycle consists of different stages, including interphase and mitotic phase. Interphase is the period during which the cell prepares for division by replicating its DNA and organelles. During interphase, chromosomes are in their uncondensed, thread-like form called chromatin and are not visible under a light microscope.
On the other hand, the mitotic phase is the stage of the cell cycle where cell division occurs. It consists of two main processes: mitosis and cytokinesis. During mitosis, the replicated chromosomes condense and become visible. They align, separate, and move to opposite ends of the cell. In cytokinesis, the cell divides, forming two daughter cells, each with the same number of chromosomes as the parent cell.
Therefore, chromosomes can only be seen during cell division when they have condensed and are visible under a light microscope. This is why the correct answer to the question is B. cell division.
