How to Learn Molecular Biology: Unlock Genetic Codes Using These Top Biology Courses

Ojash Yadav - December 03, 2020

Are you fascinated by crime dramas where forensics investigators arrive on the scene, take samples, and discover DNA belonging to a suspect? Or have you ever wondered how lab technicians in hospitals can take a blood sample, then in just a few hours, they can tell you exactly which disease you are suffering from?

The field of molecular biology holds all the answers to satisfy your curiosity. Below, we have all the collected information you might need if you want to start learning molecular biology.

What Is Molecular Biology?

As the name suggests, it is the study of biology at the molecular level. It often overlaps with the study of biology, chemistry, microbiology, and biotechnology. Molecular biology concerns the structural composition of genes and how they interact to allow an organism to function.

While studying molecular biology, you will get introduced to all the research happening in the field worldwide, covering everything from changes in genetic structure, to how to use microbes to cure diseases.

What Is Molecular Biology Used For?

There are many specific tasks that molecular biology is used for. Some of them are listed below.

  • Proteomics. Molecular biology is used to study proteomes on a large scale. A proteome is a specific set of proteins produced in a living organism. It also covers the study of how genetic material is embedded into RNA and then converted into protein.
  • Genome editing. Advances in molecular biology have led to many innovations and discoveries. Genome editing is one such innovation. It is a technique in which scientists can change the DNA of living organisms, including animals, plants, and bacteria. Using this technique, humans can create their own species of organisms. Thus, genome editing will continue to be an area of molecular biology worth studying as new developments are made.
  • DNA cloning. DNA cloning is the process of building customized DNA to use in experiments. It can be used in research on how to cure diseases or produce protein.
  • Production of new protein sequences. If a particular protein is found in a certain kind of bacteria, scientists will breed the bacteria in large quantities. When the bacteria comes of age, molecular biologists can extract the desired protein from it.

Types of Molecular Biology

To further break down this broad topic, we have listed some specific sub-sectors of molecular biology below.

Diagnostic Molecular Biology

This field of molecular biology is advancing quickly due to clinical research. It involves the use of gene mutation mechanisms, and cell formation and destruction to develop new technologies that can help find and cure diseases. It also involves isolating DNA and RNA in laboratories.

The goal of this type of molecular biology is to use clinical studies to identify the causes of diseases such as cancer, cystic fibrosis, hemochromatosis, and cerebral palsy. The DNA analysis can even be used to discover changes in single-base coding sequences, which help introduce new technologies for diagnosis.

Microbiology and Virology

As the name suggests, this is the study of microorganisms and viruses. Advancements in this area are doing wonders to cure diseases and create antibodies. The study of microorganisms also helps in developing food technology.

The use of microbiology is not limited to the medical field. It is also used in the production of wines, beer, baked goods, and pharmaceuticals. Virology is used for developments in nanotechnology, agriculture, vaccines, and cancer prevention.

Genetics and Genomics

This discipline is the study of genetic material and how its behaviors change the functioning of an organism, whether it’s a bacteria or a human being.

Gene expression data can help distinguish the phenotypic composition of the diverse ailments. This field requires extensive use of bioinformatics and data analysis .


Neuroscience is the study of physiology and how neurons function in the brain. Neurons play a major role in the functioning of organisms. Tools in molecular biology have enabled neuroscientists to make advances in recombinant DNA technology and gene sequencing.

Learning Molecular Biology

Now that we know about the distinct fields of molecular biology, let’s review the ways you can learn about the subject in depth.

How Long Does It Take to Learn Molecular Biology?
