What is a visible feature for prophase?

In prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores.

What is a visible feature for metaphase?

Prophase – Chromosomes visible. Metaphase – Chromosomes line up. Anaphase – Chromatids separate. Telophase – Two nuclei visible, cell splits.

What is the distinguishing visible feature of prophase?

Mitosis has four sequential stages: prophase, metaphase, anaphase, and telophase. In prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers. In the next phase, metaphase, the chromosomes line up along the metaphase plate.

What is visible during prophase?

During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. … The replicated chromosomes have an X shape and are called sister chromatids.

What is the most distinguishing feature of metaphase?

Metaphase is one of the stages of mitosis. During this stage, the chromosomes align in a specific manner that is very distinguishable from all of the other stages in mitosis.

What are the 5 stages of prophase 1?

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

What are the key features of prophase?

In prophase,

  • chromosomes condense and become visible.
  • spindle fibers emerge from the centrosomes.
  • nuclear envelope breaks down.
  • nucleolus disappears.

What are the 4 phases of the cell cycle?

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

What has occurred at the end of prophase?

Prophase is the first stage of cell division. Hence, the lining of the chromosomes does not occur by the end of prophase. During the prophase, the chromatin material condenses and become more compact so that the chromosomes become visible. The nucleolus and the nuclear envelope disappear by the end of prophase.
