Statistical evaluation of differential expression on cDNA nylon arrays with replicated experiments.

abstract：:DNA methylation is the best-studied epigenetic modification and describes the conversion of cytosine to 5-methylcytosine. The importance of this phenomenon is that aberrant promoter hypermethylation is a common occurrence in cancer and is frequently associated with gene silencing. Various techniques are currently avai...

abstract：:Saccharomyces cerevisiae chl1 mutants have a significant increase in the rate of chromosome missegregation. CHL1 encodes a 99 kDa predicted protein with an ATP binding site consensus, a putative helix-turn-helix DNA binding motif, and homology to helicases. Using site-directed mutagenesis, I show that mutations that a...
