WebThe 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). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions. WebThe process of mitosis is divided into four distinct stages: prophase, metaphase, anaphase, and telophase. Prophase: During prophase, the first stage of mitosis, the cell's nucleus begins to break down and the chromatids, or replicated chromosomes, become visible. The nucleolus, a small structure within the nucleus, also disappears.

The phases are defined by two major events during cell division: DNA replication (S phase) and mitosis (M phase), with intervening gap phases (G1 and G2). The cell cycle is driven by the expression of key proteins, called cyclins. bobcat eyes image

"WebMeiosis. A special form of cell division needed to produce sex cells - for example, sperm and eggs with only one copy of each chromosome. Fusion of the sex cells creates a new individual with two copies of each chromosome. Many single-celled organisms reproduce by cell division and have a single copy of each chromosome.

During this period, the cell synthesises proteins, and its size continues to increase. It is the second gap phase. Mitosis comprises five morphologically distinct phases. The mitosis phase order is— prophase, prometaphase ...

WebThe cell cycle is made up of two main stages: interphase and mitosis During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated.
