[HTML][HTML] Asymmetric directional mutation pressures in bacteria
JR Lobry, N Sueoka - Genome biology, 2002 - Springer
Background When there are no strand-specific biases in mutation and selection rates (that
is, in the substitution rates) between the two strands of DNA, the average nucleotide …

[HTML][HTML] Optimization of mutation pressure in relation to properties of protein-coding sequences in bacterial genomes
Most mutations are deleterious and require energetically costly repairs. Therefore, it seems
that any minimization of mutation rate is beneficial. On the other hand, mutations generate …

[HTML][HTML] The influence of the selection at the amino acid level on synonymous codon usage from the viewpoint of alternative genetic codes
Synonymous codon usage can be influenced by mutations and/or selection, eg, for speed of
protein translation and correct folding. However, this codon bias can also be affected by a …
