Molecular Genetics

Molecular genetics is a sub-field of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms.

In molecular terms, a gene is the entire DNA sequence required for synthesis of a functional protein or RNA molecule. In addition to the coding regions (exons), a gene includes transcription-control regions and sometimes introns. ... Most bacterial genes have no introns, whereas most genes of multicellular organisms do.

For example, molecular genetics studies demonstrated that two alleles can be codominant (characteristics… Although overlapping with biochemical techniques, molecular genetics techniques are deeply involved with the direct study of DNA. ... The DNA of any gene of interest from a donor organism
