Analysis of mitochondrial DNA insertions into a nuclear chromosome of the maize B73 line
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Mitochondrial DNA (mtDNA) is known to have integrated into the nuclear DNA of plants and animals. The purpose of this project is to investigate the on-going migration of mtDNA into the nuclear DNA of maize plants. Specific ...
The effect of caloric restriction on the mitotic rates of mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Caloric restriction has been shown to cause a number of biological changes in animals including the retardation of the aging process. Calorically- restricted animals show an average increase in life span of 30 - 50 %. In ...
A search for regulators of a yeast synaptojanin
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The yeast S. cerevisiae expresses three synaptojanins: Inp51p, Inp52p, and Inp53p. These enzymes are characterized by two specific characteristics. They contain an inositol 5'-phosphatase and a polyphosphoinositide ...
The evolving technology of bio-printing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Bio-printing is a novel method of tissue engineering that uses living cell spheroids as the 'bio-ink' and biocompatible gels as the 'bio-paper' with a three dimensional printer that deposits these aggregates into the gel ...
The effect of aryl substituted triamidoamine ligands on the structure of dioxo-molybdenum (VI) complexes
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
