Domain of a function is the type of parameters it takes as input. The domain of a sine function is angle in either degrees or radians. The function that represents the population growth of the bacteria that is tripling every minute is given by the mathematical expression,
,
where, t is time in minutes, 
is the initial population size, and 
is the population at time, t.
The domain of this function will be time, t.
The discovery of DNA, as well as understanding of its functioning and structure, may well be the most essential findings of the last century.
The impact of the discovery of DNA on medical and scientific advancement has been huge, whether it involves the manufacturing and creation of drugs to cure the deadly diseases or to identify the genes, which stimulate several of the diseases.
The understanding of DNA and its structural composition has led to the discovery of various technologies that helps in the fields like genetic testing, identifying viruses, crime investigation, production of genetically modified organisms, and various others.
Glycolysis is the common initial pathway for the both catalytic degradation pathway for ATP production and the anabolic pathway for the synthesis of hydrocarbon(gluconeogenesis)
Most important glycolysis, and then gluconeogenesis
