... In order to study a DNA fragment (e.g., a gene), it needs to be amplified and eventually purified. These tasks are accomplished by cloning the DNA into a vector. A vector is generally a small, circular DNA molecule that replicates inside a bacterium such as Escherichia coli (can be a virus). ...

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.
