Caenorhabditis elegans (Caeno, recent; rhabditis, rod; elegans, nice), is a free-living, non-parasitic soil nematode that can be safely used in the laboratory and is common around the world. (Blumenthal, T., Meyer, B.J., Riddle, D.L., Priess, J.F. (Ed.). (1997). C. elegans II. New York, NY: Cold Spring Harbor Laboratory Press. p. 1)
Separation of a cell into two daughter cells. In higher eukaryotes, it involves division of the nucleus (mitosis) and of the cytoplasm (cytokinesis); mitosis is often used to refer to both nuclear and cytoplasmic division.
In eukaryotes, the structural unit of the genetic material consisting of a single, linear double-stranded DNA molecule and associated proteins wrapped into a high order structure. During mitosis, chromosomes condense into compact structures visible in the light microscope. In prokaryotes, a single circular double-stranded DNA molecule constitutes the bulk of the genetic material.
System of protein polymers in the cytoplasm of a eukaryotic cell that provide structural integrity and the capacity for directed movement. The most abundant components are actin filaments, microtubules, and intermediate filaments.
An enzyme that phosphorylates (adds a phosphate group) to a substrate. The substrates for protein kinases are amino acids in other proteins, and they are divided into those specific for tyrosine and those specific for threonine/serine. Genes V, p.1245
