... during evolution (Syvanen 1994). The main barriers of HGT from plant DNA to microorganisms seem to be the lack of sequence homology and the non-competent status of recipient cells (Nielsen et al. 1998). Recent studies and theoretical calculations resulted in a transformation frequency of 2×10–17 und ...

Molecular evolution

Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.
