Meiosis
A type of cell division in which 4 daughter cells are produced, each having half the chromosome number of the parent cell; in plants, meiosis occurs in the sporangia on the sporophyte, and produces tetrads of haploid spores from the diploid spore mother cells; these spores typically grow into gametophytes; haploid cells cannot go through meiosis, since the haploid number of chromosomes is the minimum number a cell requires to survive.

Mitosis
The division of the cell's nucleus and nuclear material of a cell; consists of four stages: prophase, metaphase, anaphase, and telophase. Mitosis occurs only in eukaryotes. The DNA of the cell is replicated during interphase of the cell cycle and then segregated during the four phases of mitosis.

Metaphase
The stage of eukaryotic cell division (mitosis or meiosis) in which the chromosomes line up at the equator of the cell.

Mitochondria
Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose. Singular: mitochondrium.

Metabolism
The chemical activity that occurs in cells, releasing energy from nutrients, or using energy to create other substances, such as proteins.

Macrolide
A group of drugs (typically antibiotics) whose activity stems from the presence of a macrolide ring, a large lactone ring to which one or more deoxy sugars, usually cladinose and desosamine, are attached. The lactone ring can be either 14, 15 or 16-membered. Macrolides belong to the polyketide class of natural products.

Minocycline
Minocycline hydrochloride, also known as minocycline, is an antibiotic of the tetracycline class. It is marketed under several trade names, including Minomycin, and Dynacin. It is primarily used to treat acne.
