Molecular Genetics is a branch of genetics which studies the structure and function of genes at a molecular level. It involves the analysis of DNA, RNA, and proteins to determine how genes interact with each other and with their environment to determine the phenotype, or the physical characteristics of an organism. Molecular genetics offers tools for studying and manipulating the genetic code of an organism, from diagnosis of genetic disorders to DNA technology such as gene editing. Molecular genetics studies the roles and effects of genes on a cellular level. Using techniques such as polymerase chain reaction (PCR), gene cloning, and sequencing, researchers can investigate the role of a gene in a particular pathway or disease. By analyzing the genetic code of an organism, scientists are better able to understand the links between genetic sequences and phenotypic traits, or the traits observable in the physical characteristics of an organism. The analysis of DNA can also be used to answer genetic questions. Using DNA fingerprinting, for example, investigators can determine whether individuals are related or not by comparing their DNA sequences. Once a genomic sequence for an organism is acquired, genome-wide association studies can be conducted which use statistical methods to find correlations between genetic variants and certain traits. With the knowledge gained from such studies, researchers can develop gene-based therapies which target the root cause of certain illnesses. Molecular genetics is also responsible for advances in biotechnology such as gene therapy and gene editing. Using gene editing, scientists are able to make genetic modifications to organisms that could potentially help treat genetic diseases. Moreover, gene therapy can be used to introduce beneficial DNA into an organism, which could potentially help treat or even cure complex genetic diseases. Ultimately, molecular genetics is playing an ever-increasing role in our understanding of the underlying genetic mechanisms of life. With advances in technology, scientists are able to go beyond traditional methods of analysis, resulting in a more accurate understanding of how genes interact with the environment. With further research into the science of molecular genetics, we can expect to use gene-based therapies to treat various genetic diseases in the future.
