Ligands (in biochemistry)
A RNA simulation method developed by the MIT. In general a molecule or ion that can bind to (interact with) a protein molecule. For example, a pharmaceutical that binds to a receptor protein molecule on the surface of a cell may be called a ligand.

Life cycle
The successive stages through which an organism passes from fertilized ovum or spore to the fertilized ovum or spore of the next generation. The artificial segments of the life span. Each segment represents a developmental period: birth, maturity, aging, and dying. All of the developmental history of an organism, whether in a free living condition…

White blood cells that protect the body from infectious diseases and provide immunity. A diverse family of nucleated cells that has many immunological functions. Any of the white cellular components of blood or lymph. The white…

Leucine
An essential branched-chain amino acid important for hemoglobin formation. Rarely limiting in foods; one of the branched-chain amino acids. A monocarboxylic essential amino acid. Leucine is a branched-chain, essential amino acid. It is needed for COOH synthesis of proteins and can be used for energy production within the muscle 2 cell as well. Metabolism of…

Kinetochores
Large multiprotein complexes that bind the centromeres of the chromosomes to the microtubules of the mitotic spindle during metaphase in the cell cycle. A protein disk attached to the DNA of the centromere that connects a pair of chromatids during cell division. A spindle fiber is in turn attached to the kinetochore.
