Do Noncoding and Coding Sites in Angiosperm Chloroplast DNA Have Different Mutation Processes?

Genes - 5 Jan 2023

Morton Brian R

Abstract excerpt

Fourfold degenerate sites within coding regions and intergenic sites have both been used as estimates of neutral evolution. In chloroplast DNA, the pattern of substitution at intergenic sites is strongly dependent on the composition of the surrounding hexanucleotide composed of the three base pairs on each side, which suggests that the mutation process is highly context-dependent in this genome. This study...
