To search for evolutionary forces that might act upon transcript length. we use the singular value decomposition (SVD) to identify the length distribution functions of sets and subsets of human and yeast transcripts from profiles of mRNA abundance levels across gel electrophoresis migration distances that were previously measured by DNA microarrays. We show that the SVD identifies the... https://www.roneverhart.com/Lifestyle-Mobility-Aids-P2-Portable-Oxygen-Concentrator-with-Carry-Case/
