cell replacement
Normal cell activities occur not in mitosis, but in a cell cycle in a general. This part of cell cycle is called interphase. Mitosis starts when the cell starts dividing, not when a cell is carrying out normal function.
The stage of the cell cycle during which the nucleus divides is called mitosis. Mitosis is part of the M phase of the cell cycle and involves the separation of the duplicated DNA into two identical sets, resulting in two daughter nuclei.
The primary function of mitosis during the cell cycle is to ensure the accurate division of a cell's genetic material, resulting in two genetically identical daughter cells. This process is crucial for growth, tissue repair, and asexual reproduction in organisms. Mitosis involves several stages—prophase, metaphase, anaphase, and telophase—where chromosomes are properly aligned, separated, and distributed to the daughter cells. Ultimately, it plays a key role in maintaining genetic stability across cell generations.
Many organisms use mitosis and meiosis. Namely, all eukaryotes probably use mitosis and meiosis. Only bacteria (prokaryotes) would not divide by mitosis and have no mechanism for meiosis as their chromosomes differ from those of eukaryotes.But eukaryotes all have the capacity for mitosis and meiosis. Eukaryotes include all animals, plants, protists and fungi.Thus, since pigs are animals (and are thus eukaryotes), then indeed they have cells that divide by mitosis and meiosis. Their body cells (somatic cells) divide by mitosis (for growth and repair). Their gametes (sperm cells and ova) are produced by meiosis as these cells must be divided to a haploid form before copulation and fertilisation. Two haploid gametes would fuse (fertilisation) to restore the resulting cell (zygote) to a diploid form. The zygote grows into a new piglet via mitosis.
No, but mitosis is a part [the M-phase] of the Cell cycle.

Nuclear division by mitosis or meiosis
No, but mitosis is a part [the M-phase] of the Cell cycle.
The shortest stage of the cell cycle is m-phase.
1. Nuclear division (two identical nucleii are formed) 2. Cytokinesis (the actual 'splitting' of the cell)
The stages of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). G1 involves growth and normal cell functions, S phase is when DNA replication occurs, G2 prepares for cell division, and M phase involves cell division where mitosis and cytokinesis occur.
The DNA is the molecule that provides theinformation for cell growth and function.
Mitosis occurs first in the cell cycle before meiosis.
