The study which studies the differences in DNA structures and estimates the variation of the molecule in different organisms. The topic is considered to be the subfield of biotechnology, biochemistry, cellular biology and molecular biology. Inducing mutations in a gene can link a gene to a specific phenotype. Under this subject, mutation are linked with genetic conditions to determine treatment for a variety of genetic diseases. Figuring out DNA structure was the most important invention which emerged as a stepping stone in molecular genetics. Central dogma is the basis of genetics which plays a key role this subject of study. Forward genetics is used to identify genes or mutations happened with genes that produce a specific phenotype. Mutations can be random or intentional and reverse genetics technique is used understand the phenotype formed as a resultant of intentional mutation in a gene of interest. Important facts about the topic is explained in the presentation.
