Study of the flow of information as it occurs within cells, particularly involving various forms of nucleic acid sequence.
Molecular genetics is the study particularly of replication, transcription, and translation as well as the structural basis of the functioning of genes along with various parasites that consist predominantly of DNA or RNA. See central dogma.
Included among the latter, for example, are plasmids and transposons which are sub-chromosomal pieces of DNA that are either not integrated or integrated, respectively, into the larger chromosomes of a cellular organism.
The field of molecular genetics also can be considered to represent a hybrid between the biochemical and the genetic study of life, that is, of biochemistry and genetics that can trace its origins to approximately the 1950s and most notably to the discovery by Watson and Crick of the structure of the DNA double helix in 1953.
