WebbProphase: The chromosomes condense into X-shaped structures that can be easily seen under a microscope. Each chromosome is composed of two sister chromatids, containing identical genetic information.

"WebbProphase is that phase of mitosis and meiosis where the duplicated genetic material undergoes condensation in the nucleus. In particular, the chromatin (a combination of DNA and proteins) of the parent cell, is condensed during prophase. (The condensed chromatins are referred to as chromosomes.)

WebbThe four phases or steps of mitosis are as follows; Prophase Metaphase Anaphase Telophase Prophase It is more likely a preparatory phase to begin the division of chromosomes. During interphase, the nuclear material in cells is in the form of loosely packed chromatin to promote gene transcription. WebbLet's go over the stages of mitosis in more detail. Prophase. During prophase, the first stage of mitosis, the DNA chromosomes condense into sister chromatids and are now visible. The centrosomes start to separate to opposite sides of the cell, producing long strands called spindle microtubules, or mitotic spindles, as they move through the cell.

Webb18 nov. 2024 · Stages of Mitosis Prophase Each chromosome is made of two genetically identical chromatids, joined by a centromere. During DNA replication, genetic material is loosely packed as chromatin. However, … Meiosis involves two rounds of chromosome segregation and thus undergoes prophase twice, resulting in prophase I and prophase II. Prophase I is the most complex phase in all of meiosis because homologous chromosomes must pair and exchange genetic information. Prophase II is very similar to mitotic prophase. Prophase I is divided into five phases: leptotene, zygotene, pachytene, diplotene, and diakinesis. …
