Explanation:
Detailed explanation-1: -Complete answer: The cell component visible only during cell division is the chromosome. In a nondividing cell, the genetic material that is known as DNA is present as chromatin fibers. Chromosomes are visible only during certain stages of cellular division.
Detailed explanation-2: -During interphase, the genetic material is called chromatin and can NOT be clearly seen because it isn’t tightly coiled. In fact, a nucleus and nucleolus are clearly visible. When prophase begins, the DNA molecules are progressively shortened and condensed by coiling, to form visible chromosomes.
Detailed explanation-3: -A chromosome contains many genes. A gene is a segment of DNA that provides the code to construct a protein.
