Synonymous and non-synonymous transitions/transversions vividly disclose purifying selection in Escherichia coli coding sequences

P. K. Beura, R. Aziz, P. Sen, S. Das, N. D. Namsa, E. Feil, S. S. Satapathy, S. K. Ray

The paper develops a method to estimate the ti/tv ratio in E. coli coding sequences by accounting for codon degeneracy and pretermination codons, revealing insights into purifying selection.

The transcribed intergenic regions exhibit lower frequency of nucleotide polymorphism than the untranscribed intergenic regions in the genomes of Escherichia coli and Salmonella enterica

P. K. Beura, P. Sen, R. Aziz, S. S. Satapathy, S. K. Ray

This study compares polymorphism frequencies between transcribed and untranscribed intergenic regions in E. coli and S. enterica, finding that transcribed regions have lower polymorphism rates due to repair mechanisms and sequence features.
