During interphase, which is the longest phase of the cell cycle, several important processes occur. A. DNA Replicates during Interphase: One of the key events that takes place during interphase is DNA replication. This process ensures that each chromosome in the cell's nucleus is duplicated, resulting in two identical copies called sister chromatids. DNA replication is crucial for cell division as it ensures that each daughter cell receives a complete set of genetic information. B. Chromatin is made of DNA: Chromatin refers to the complex of DNA and proteins that make up the chromosomes within the nucleus of a cell. It is composed of DNA molecules tightly coiled around proteins called histones. During interphase, the chromatin is in a less condensed form, allowing for easier access to the DNA for various cellular processes such as transcription and replication. C. Genes are found on DNA: Genes are segments of DNA that contain the instructions for building and functioning of specific proteins or RNA molecules. They are the fundamental units of heredity and determine various traits and characteristics of an organism. Genes are located on the DNA molecule, and during interphase, they are accessible for gene expression and regulation. Therefore, all of the statements A, B, and C are true. DNA replicates during interphase, chromatin is made of DNA, and genes are found on DNA.
