Among the expansions that Molecular Biology has allowed, we find: 1) facilitating research of the processes underlying the expression and inheritance of genes as part of genetics studies; 2) the contribution of baseline knowledge for the development of more assertive diagnoses and treatments in diseases of genetic and metabolic origin; 3) the development of genomic therapies as a new curative option; 4) the biotechnological contributions that have made possible the genetic modification of organisms, for the improvement in their agricultural use; 5) the advancement of research on the various forms of cancer and their potential treatments; 6) understanding of the ways in which medications act metabolically, increasing the discoveries about cholinergic and antagonistic reactions, thereby transforming the course of pharmacology; 7) the boost in the rise and development of study areas corresponding to pathogenic microorganisms that cause infectious diseases that are more difficult to detect; 8) the implementation of molecular analyzes that speed up diagnostic processes for a large variety of pathologies and metabolic alterations, as well as the study of DNA and the genome for multiple purposes; and 9) the production of vaccines and research into immune mechanisms.

Among the modern specialties of biology with the greatest boom in recent decades, molecular biology stands out for multiple reasons. reasons, since by focusing on the study of the molecular processes existing at the cellular level, it has paved the way towards an understanding ever deeper understanding of the physicochemical details occurring in the organism that until the middle of the last century had been unobservable.

The bases of existence

Study the molecules that have allowed the existence of life, from the macro level where proteins, carbohydrates, and lipids are located, as well as the DNA itself and the various forms of RNA, has given science the ability to interpret the processes that have made the anatomical and physiological conformation possible. of species, at the same time it has opened the doors for a more precise and exact determination of the evolutionary lines existing between species, helping to establish a greater order within phylogenetic studies, which has generated a large number of modifications in the knowledge about the species that had been inferred from Darwin's initial approach, demonstrating all the validity of his reasoning and how deeply he is involved with the molecular bases of life.

Certainly, one of the greatest leaps in biological sciences that marked a forceful dividing line between before and after its discovery, It was the moment in which molecular biology managed to decipher the human genome completely, thereby also clearing the way towards understanding of our true origin as a species and allowing us to reevaluate the successes and failures of what we had concluded until the end of the year. 20th century regarding the evolutionary sequence of our history and the parental grades existing among the different ethnic groups in which we we have derived. All this new information provides great help for the dismantling of racial paradigms, based on the presumption of purity and superiority of some traits over others, beliefs that once served as triggers for the most cruel and catastrophic wars, so molecular biology has also contributed to the well-being of societies through the moral changes that promotes.

Engineering with life

The experimental manipulation of molecules essential for life, such as proteins, has provided the conditions for the development of an area dedicated to development of molecular variants that seeks to create positive alterations with the purpose of improving the large productive processes necessary for our survival, such as such as agriculture, developing variations of species so that they can be more resistant to environmental adversities, pests and diseases, in order to increase the crop yield, while reducing their costs, as part of the strategies promoted for the reduction of hunger and poverty in the world, but also for the reduction of contaminating factors linked to the area, such as the use of agrochemicals for chemical fertilization of soils and even more risky pesticides and fungicides.

A more mental projection on molecular biology directs our gaze towards the extraordinary advances that it has allowed in the field of neurosciences, where he has highlighted the neuroplastic capacity that allows, among other phenomena, the recovery of damage that could occur neurons suffer, basic information for research into neurodegenerative diseases and their potential treatments, cures and measures preventive.

Inside the science of molecules

In addition to the advances that molecular biology promotes for the study of microbiology, allowing an increasingly detailed understanding of the molecular interactions existing between microorganisms and the species they pathologically affect, it also guides the study of pharmacological actions with which to combat the smallest pathogens, in way of being able to develop increasingly more efficient drugs, while seeking to reduce their potential side effects and adverse reactions, thanks to the increasingly close link between biological knowledge, its potential uses and the bioethics under which it must be governed, in order to continue guaranteeing the right to life for all species existing.
