DNA MUTATIONS AND THEIR REPAIR
... Point mutations are usually caused by chemicals or malfunction of DNA replication and exchange a single nucleotide for another. Most common is the transition that exchanges a purine for a purine or a pyrimidine for a pyrimidine (A ↔ G, C ↔ T). A transition can be caused by nitrous acid, base mispair ...

A Degenerate ParaHox Gene Cluster in a Degenerate Vertebrate
... Intriguingly, Blast searches revealed a sequence 11 kb downstream of the M. glutinosa Gsx gene, in the same orientation, with high similarity to the second exon of vertebrate Xlox genes, including the homeodomain. However, this sequence has numerous nonsynonymous changes and a frameshift between the ...
