What is Spireme stage in mitosis? , spireme (spī’rem, spī’rēm), Term formerly applied to the first stage of mitosis or meiosis (prophase) during which extended chromosome filaments have the appearance of a loose ball of yarn, on the incorrect supposition that the filaments were continuous and later broke apart to form individual chromosomes.
What is mitosis vs meiosis? Mitosis is a process where a single cell divides into two identical daughter cells (cell division). facts What is meiosis? Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
What is the name given to the original cell before it divides? How Do Cells Know When to Divide? In cell division, the cell that is dividing is called the “parent” cell. The parent cell divides into two “daughter” cells.
Why do cells divide? Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.

How many stages of mitosis are there?
Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase. Each phase involves characteristic steps in the process of chromosome alignment and separation.
What does Spireme mean?
Medical Definition of spireme. : a continuous thread observed in fixed preparations of the prophase of mitosis that appears to be a strand of chromatin but is generally held to be an artifact.

Hint: The fibres that are formed in between the centromeres of the homologous chromosomes are interzonal fibres. This is usually seen in metaphase I stage.

What are the 5 sub phases of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
What are the stages of cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
