Meiotic mapping of yeast ribosomal deoxyribonucleic acid on chromosome XII.

摘要: We have used meiotic mapping techniques to locate the position of repeating ribosomal DNA (rDNA) genes yeast Saccharomyces cerevisiae. found that rDNA are located on right arm chromosome XII, approximately 45 map units centromere distal gene gal2. Together with data from previous studies, this result suggests tandem array contains at least two junctions non-rDNA chromosome. In addition, we observed segregation patterns consistent recombination within in 3 59 tetrads examined. Images
