Detailed explanation-1: -Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Detailed explanation-2: -Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes-which were duplicated during S phase-condense and become thousands of times more compact than they were during interphase.

Detailed explanation-3: -In the first stage of prophase I, leptotene (from the Greek for “delicate"), chromosomes begin to condense. Each chromosome is in a haploid state and consists of two sister chromatids; however, the chromatin of the sister chromatids is not yet condensed enough to be resolvable in microscopy.

Detailed explanation-4: -Meiotic prophase I is subdivided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis.

Detailed explanation-5: -The first prophase of meiosis is the longest and consists of three main stages. First, chromatin condenses into chromosomes, next homologous chromosomes physically touch one another, and finally, synapsed chromosomes communicate genetic information to one another.
