What is the difference between the study of 'microbiology' and 'molecular biology'?

Microbiology involves study of microorganisms like bacteria, fungi, viruses etc. on the other hand molecular biology is study of biomolecules(like DNA, RNA & Proteins) and their interactions in order to study molecular basis of any biological phenomenon. So microbiologist can use techniques of molecular biology to study any process or phenomenon in microorganism at molecular level.

Molecular Biology Vs Microbiology

Microbiology Vs Molecular Biology

I've taken both classes. Molecular Biology should be called Microbiology 2, because it's more of the Behind the Scenes information that you learn. In Microbiology you learn the system, in Molecular Biology you learn Why It Works The Way it Does.

I highly recommend taking Micro first, then Molecular Biology. Taking Chemistry will also help you get through Molecular Biology easier.

The other responses are correct about microbiology being the study of protists, bacteria, archaea, some fungi, & viruses. Molecular biology focuses on biological molecules & structures. Molecular biology has a strong focus on the chemical aspects of biology & covers both eukaryotic & prokaryotic forms. A good microbiology program will ensure that you have a solid foundation in biochemistry because biochem/molecular biology is very important at that scale. If you want to pursue a career in biology, you should strongly consider going to graduate school & get a PhD. Either major will give you many options as to what to study in grad school. (You can stay a molecular bio undergrad & study microbiology in grad school). Molecular biology is a less specialized major, so you would have more options as to what to study in grad school. However, if you think you want to pursue microbiology as a career, having that undergraduate major would give you a strong foundation on that field. My medical microbiology prof is a Senior Scientist at the CDC. He is a microbiologist researcher who focuses solely on molecular biology to make better diagnostics for pathogenic infections.

Microbiology is the study of microscopic life forms. Bacteria, viruses, parasites, fungi, prions= Microbes.

Molecular biology is the study life from a molecular perspective. They will look at how DNA expression is controlled in a living cell. They also look at how various cell processes occur. They may work with microbes however they also work with animal or human cells.

Therefore some molecular biologists are also microbiologists but not all molecular biologists are microbiologists.

The difference? Much of what is said above is on point and I can't add to this; only that there exists, say, a tree with respect to the untold number of branches of Biology now, so broad is it, so complex has it all become -- from Anatomy and Physiology to Organology to Histology to Cytology, to Molecular and ever smaller till reaching that of the study at the atomic and subatomic levels in Biology.

And so, one may see that a fine way to distinguish these is by order of magnitude of the living systems measured, each of which sub-branches overlaps with the others, such as genetics and biochemistry and more; because they all are seen to interconnect. In fact, some teachings combine molecular biology with biochemistry, or chemical biology -- so interchangeable are these.

And all interconnect anyway; only are the life scientists now conceding ever more that they interconnect ... and at once. Yet scientists have always reduced matter to its least first before evidencing the entirety. Thus one need only focus on some one niche and take up the applications of that to discern which sub-branch interests them most to denote the relationships more than the differences.

And because of this interconnection, nanotechnology comes into play by reason and benefit of electron microscopy; and because of increasing emphases on nanotechnology, atomic- and biophysics come to bear as well; because underpinning molecular biology is the atomics involved -- especially that of the carbon atom -- of the molecules of the very living systems themselves.

if u get the choice which one to study take the microbiology option very interesting and very hands on.

while the two are the focus of biologists for the milenium;microbiology is the study of microorganisms,and mol biology on the other hand is the study of their biochemistry and that of higher organisms
