Extrachromosomal elements in lower eukaryotes:
- eds.
While most genes are chromosomal, the nonchromosomal genes have played a disproportionate role in molecular biology, in part because of their easy accessibility and in part because they represent the most mobile portion of a cell's genome. Fungi, yeasts, protozoa, slime molds, algae, and other single-celled nucleated species, have recently gained dramatic popularity with the development of transformation methods for Saccharomyces, Neurospora, Schizosaccharomyces, Dictyostelium, and others of this group. The realization that Saccharomyces has oncogenes, RNA tumor viruses, intervening sequences, and all the mitotic, mitochondrial, and other structures typical of so-called ''higher'' eukaryotic organisms has confirmed the use of such organisms as model systems. Their use in biotechnology also shows great promise. The study in lower eukaryotes of mitochondria and chloroplasts has yielded many insights into similar structures in higher organisms as well as many unexpected finds, such as mechanisms of intron excision and the biology of introns, RNA catalysis, variation of the genetic code, and mechanisms of protein import across membranes.
