In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
Biological development, the progressive changes in size, shape, and function during the life of an organism by which its genetic potentials (genotype) are translated into functioning mature systems (phenotype). Most modern philosophical outlooks would consider that development of some kind or other.

In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. Interphase.
- When are mutations more likely to occur in the cell cycle? Is there a specific stage in mitosis or p...Interesting question! I'm not sure how well studied this is, but the consensus seems to be that mutations mostly happen during DNA synthesis — i.e....
- what is the difference between DNA & RNA?to be more specific, there are 3 main RNA types: mRNA (matrix) - is copied from DNA, to later copy proteins off it, rRNA (ribosomal) - is what ribo...
- Why do cells divide than growI think they grow to accommodate for the doubling of new organelles and the split of DNA in later stages. After that, then they split. I hope it he...
- in other words, you go from a cell to a cell.Not necessarily. You go from a cell to two cells, or even four during meiosis.
- What is the DNA inside a cell called? genetic material or chromosome?DNA is genetic material, and the way it is physically present in our nuclei is by being condensed into chromosomes.
- How long does it take for a cell to fully grow? Days, weeks?It really depends from cell to cell. Division and growth of cells take 24 hours for many human cells, but liver cells take more than a year and neu...
- In my textbook, it says the chromatin fibres condense into chromosomes in prophase. However, here it...Right after the cell is born, the DNA is in the form of chromosomes, but in early G1 phase, the chromosomes break apart into chromatids and are onl...
- How does a cell copy its DNA?Hi Thandeka, The way a cell copies its DNA is actually a pretty complex (but very interesting!) process. There are quite a few steps to this, but t...
- About the mitosis. Why does a cell have to divide? Is it because our body needs more cells because o...Many cells have a limited life span, so mitosis needs to occur so that healthy, living cells can be maximized.
- Can you give a short summary of mitosis using the steps??The cell goes through 4 steps (prophase, metaphase, anaphase, and telophase.) The cells at the end of the process also have the same amount of chro...
The three stages of interphase are called G 1, S, and G 2. G 1 Phase. The first stage of interphase is called the G1 phase, or first gap, because little change is visible. However, during the G 1 stage, the cell is quite active at the biochemical level.
May 9, 2024 · 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). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
The 4 Phases of Mitosis: Prophase, Metaphase, Anaphase, Telophase . So what are the stages of mitosis? The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we’ll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis.
