Comparison of the nucleotide sequences of a yeast gene family. II. Analysis of spontaneous deletions and insertions.


We compared the nucleotide sequences of 3 yeast invertase genes in regions where the homology is better than 90%. In the noncoding region 40 gaps of 1-61 bases were found. This is about half as much as the nucleotide substitutions in the same sequences. We grouped the gaps into 5 categories by their length and the characteristics of their sequences. Group I… (More)
