Molecular Biology

A field of biology concerned with biological phenomena in terms of molecular (or chemical) interactions; it differs from biochemistry in that the latter is concerned primarily with the chemical behavior of biologically important substances and analogues thereof, and differs from other fields of biology in its emphasis on chemical interactions, especially those involved in the replication of DNA, its transcription into RNA, and its translation into or expression in protein, i.e., in the chemical reactions connecting genotype and phenotype.
