Molecular biology chiefly studies the interactions between the various systems in the cells, or studying the formation, structure and function of the macromolecules essential for life, such as nucleic acids (DNA and RNA) and proteins, and particularly their role in the replication of cells and transmission of genetic information.
Molecular biologists study the molecular basis of living organisms. They study how genetic information can be encoded in the molecules of deoxyribonucleic acid (DNA) and how this information can be used for the synthesis of all other molecules that make up living organisms. To this end, molecular biologists have increasingly explore the genetic control of these molecules in order to define developmental, cellular and subcellular changes that occur during the dynamic processes of life. One of the basic research of molecular biologists is how the genetic information in DNA can not be changed, and how they change and how they can cause disease.
Extensive and evidential growth sciences in recent decades changed the image of science in modern society. The molecular biology is one of najpopulariziranite natural scientific disciplines and imaneprocenlivo impact on many applied fields, such as medicine, pharmacy, veterinary medicine, agriculture, biotechnology and other sciences, and applied research in industry. The main focus of research in the field of molecular biology is aimed at discovering the regulation of gene expression in organisms and complex relationships of interrelated genes and gene products involved in the regulation.
In all organisms despite the extreme diversity of wildlife genetic information is incorporated into the structure of nucleic acids in almost identical manner.
The 21st century is an era of development of molecular biology, and thus the development of its various areas (sub-disciplines). These include areas whose name ends with the suffix omics, etc. ” Omics ” sciences such as genetics ( genomics ), proteomics ( proteomics ) and metabolemikata ( metabolomics ).
” Omics ” sciences are particularly important as they serve to study the characteristics and quantity of biological molecules which participate in the structure, function and dynamics of an organism or microorganism.
In the wake of “omics” era that produces huge databases of molecular components of cells, it is increasingly important to discover underlying mechanisms that allow cells have differentiated properties and coordination of activities for the establishment of basic systems that define living cell . Daily coming to new insights continuously expands the potential of molecular biology to provide answers to key questions animals.
The application of more modern equipment in all molecular biology will allow solving more problems to human health or detect prichiteli various diseases in humans. Thus, molecular biology will dopridonese for faster and greater development of medicine and the pharmaceutical industry in the 21st century.
