Use it or lose it? Researchers investigate the dispensability of our DNA

... forces at work. "With this in mind, we set out to examine the genomic data, much as someone would examine archaeological data, in search of similar deletion events that have happened naturally, and more importantly, were retained in the wild." "An analogy I like to entertain is that of plate tectonics: ...

Direct Monitoring of Solid-Phase Peptide Synthesis by MALDI-TOF MS

... step would have been diagnosed. Figure 2 shows some of the minor peaks in the spectrum taken after step 13. Small amounts of deletion peptides are seen in addition to small peaks representing residual Pbf (Arg-protecting group). These are due to released Pbf attacking, for example, ...

Protein Truncation Tests Using the DCode System

... fact that no normal product is observed in this lane usually indicates a homozygous mutation. Sequencing of cDNA indicated a deletion of 174 bp, corresponding to the entire exon 26. Because this cDNA mutation would result in an in-frame deletion, the final ...
