Molecular Biology is the investigation of science at a sub-molecular level. The field covers with different regions of science, especially hereditary qualities and natural chemistry. Molecular Biology primarily frets about understanding the connections between the different frameworks of a cell, including the interrelationship of DNA, RNA and protein combination and figuring out how these communications are controlled. Plant Molecular Biology is the exploration of the sub-molecular basis of vegetation. It is especially worried about the procedures by which the data encoded in the genome is showed as structures, procedures and practices.
Plant Biochemistry is the term used for the chemical processes used by plants. Some of these processes are used in their primary metabolisms like the photosynthetic Calvin cycle and Crassulacean acid metabolism. Others make specialized materials like the cellulose and lignin used to build their bodies, secondary products like resins and aroma. Plant Biochemistry is not only an important arena of basic science explaining the molecular function of a plant but is also an applied science that is in the position to contribute to the solution of agricultural and pharmaceutical problems. By controlling information flow through biochemical signalling and the flow of chemical energy through metabolism, biochemical procedures give rise to the complexity of life. Today, the main focus of Plant Biochemistry is in understanding how biological molecules give rise to the processes that occur inside living cells, which in turn relates greatly to the study and understanding of whole organisms.
