Studying the development of molecular biology, the structural relationships and roles of nuclear DNA molecules holistically starting from the function of DNA as an initiator to a regulator of all metabolic function mechanisms comprehensively with every phenotypic phenomenon that can be seen and felt. Examining gene expression related to transcription, translation and expression control at the molecular level in prokaryotes and eukaryotes; DNA replication mechanisms; gene regulatory mechanisms; extrachromosomal DNA; proteomics and genomics; and applications of molecular biology in various fields of life through theoretical studies and assignments.
