"Where's there water on earth, you will find life as we know it." -Neil deGrasse Tyson
Since biology is the study of all living things, biologists from all over the world conduct experiments and analyse microorganisms to understand the universe better. In the process, many biologists across different sectors of study develop an appreciation for planet earth.
Also, another positive aspect of scientific disciplines such as biology is that no matter where you live, what your religious beliefs are, and what language you speak, the rules of the natural world and how they are studied is the same. Biology truly is a subject that transcends differences and makes all acquire fundamental truths of planet earth no matter how much money we have in our bank account.
Therefore, without further ado, we shall look at many different aspects of experimental biology and how they can be studied.
Experimental vs Theoretical Biology
Since biology is one of the most significant academic disciplines that help us become better prepared to answer life's massive questions, solve critical biological issues, and develop a better comprehension of our bodies, which opens the doors to many potential careers, it's worth exploring.
However, some might ask themselves, what is the difference between experimental and theoretical biology? To answer that question, we must first understand what is experimental biology and also define theoretical biology.
First and foremost, in the simplest of definitions, experimental biology can be understood as a type of biology that conducts experiments and tests in the laboratory to see if scientists hypothesis' are correct or not. Experimental biology is undertaken to better understand phenomena from the natural world. A lot of trial and error is involved in experimental biology.
It highlights various methods employed in experimental biologies, such as molecular, biochemical, biophysical, microscopical, and microbiological biologies.
Secondly, theoretical biology is the complete opposite since it has to do with uncovering biological theories through mathematics and not through trial and error. Theoretical analysis is used in theoretical biology, and mathematical models are used. Theoretical biology has other names, such as mathematical biology and biomathematics.
Biomathematics emphasises the need for maths to solve biological issues, and, often, technology is utilised to more efficiently explain complex concepts.
So, what is the difference between theoretical and experimental biology? While both are useful in their attempts to comprehend biology, it's worth stating that experimental biology requires more testing in the laboratory, whereas theoretical biology involves a lot of mathematics.
Although they are very different in style, the approach of experimental and theoretical biology is the same: to help us better comprehend our natural world.
Molecular Method in Experimental Biology
Because experimental biology encompasses many specific areas of study, various experiments and trials are conducted using molecular methods. By understanding the most powerful molecular biology techniques, we can comprehend molecules and cells from the natural world completely.
So, without further delay, the following are the four most recognisable techniques from molecular biology:
- Blotting and Probing: through the process of blotting and probing molecules, biologists may transfer proteins from either DNA or RNA to carriers such as nitrocellulose or a nylon membrane. It's worth stating that there are four blotting types: Southern, Northern, Western, and Eastern.
- Gel Electrophoresis: using gels and biological substances, the process of gel electrophoresis relies on the fact that DNA, RNA, or other proteins can be separated by an electric field. Different gels are used in this molecular method, such as agarose, polyacrylamide, and starch.
- Molecular Cloning: for the past fifty years or so, biologists have become obsessed with the prospects of cloning species. Dolly, the Sheep, ring a bell? Since attempts at cloning require extensive knowledge of cells and molecules, molecular biologists analyse the vector and try to put puzzle pieces together.
- Polymerase Chain Reaction (PCR): probably one of the most versatile ways of copying DNA, the Polymerase Chain Reaction (PCR) is potent and must be completed by experienced scientists in a laboratory. PCR's can complete tasks like introducing restriction enzyme sites to the ends of DNA molecules and mutate particular bases of DNA with molecules.
Other techniques that are well-known in molecular biology include the cutting and pasting of DNA, chromosome integration, extraction of DNA, and cellular screening, to name a few. But, again, hiring a personal molecular biology tutor will significantly help you learn more effectively.
Biochemical Method in Experimental Biology
With so many different types of biology that focus on unique aspects of the natural world, it can be quite a task to differentiate one from the other and know how subdisciplines are similar. For example, if we consider experimental biology, there are plenty of related genres of biology that relate to it.
However, it's worth stating that biochemical biology or biochemistry is one of the fields of biology that closely relate to experimental biology because a lot of testing is accomplished. But, what is biochemical biology? In layman's terms, biochemical biology is the study of the chemical process related to living organisms.
Biochemical biology is the perfect mix between biology and chemistry and how they relate to one another.
The following are the three genres of biochemistry that are recognised by students and teachers alike:
- Structural biology,
Also, it's worth stating that biochemistry is one of the leading sectors of biology since it pushes us to understand and better explain some of life's most severe problems. Through biochemistry, we know how our cells work, and other aspects of the human body since biochemical biology boasts the following four properties that are worthy of study:
- Nucleic Acids.
To better comprehend how the previously mentioned properties react in the human body, various methods are employed as part of biochemistry, such as the following:
- Molecular Genetics,
- Protein Purification,
- Structural Determination,
- Interactions Between Biomolecules.
To learn more about biochemistry's specific properties and methods, we highly recommend hiring a Superprof biology tutor to guide you.
Microscopical Method in Experimental Biology
To complete the experimental biology work that must be accomplished in the lab, it's worth stating that there are a few indispensable instruments that biologists must use. Such as? First and foremost, the examination of biological matter isn't possible without a microscope.
A microscope is so vital in biology that a specific field of study known as microscopy is closely related to the concepts of natural science and biology. To better understand microscopy, it can be defined as an academic discipline that uses microscopes to view objects and biological matter otherwise naked to the human eye.
Microscopy involves a lot of time analysing matter under distinct types of microscopes. It's important to state that there are four main categories of microscopy: Optical, Electron, Scanning-probe Microscopy, and X-Ray Microscopy.
Microscopy is closely related to experimental biology since a lot of time is spent in the lab conducting experiments with microscopes to see whether things are accurate and what additional aspects of the natural world may be learned.
Are there any specific techniques of microscopy? Absolutely! The following are a few methods of microscopy to understand the field in question better:
- Bright Field,
- Oblique Illumination,
- Dark Field,
- Phase Contrast,
- Dispersion Staining,
- Two-photon microscopy.
All of the previously mentioned techniques greatly aid biologists in using their microscope to observe samples of matter such as molecules, cells, and participles. To learn more, why not hire a microscopy tutor on Superprof to show you how things are done effectively? You won't regret it!
Microbiological Method in Experimental Biology
Another important branch of experimental biology is the ever essential subdiscipline of microbiology that studies bacteria, viruses, fungi, prions, and algae from the natural world. Microbiologists conduct many experiments in the lab to save people's lives by inventing medicine and preventing serious viruses from spreading.
Also, through microbiology, scientists comprehend how different microorganisms may work together in a specific ecosystem.
Since microbiology is such an extensive sector of biology, it has various branches such as the following:
- Microbial genetics,
- Molecular microbiology,
- Medical microbiology,
- Pharmaceutical microbiology,
- Industrial microbiology,
- Food microbiology,
- Environmental microbiology,
- Agricultural microbiology.
All of the previously mentioned branches of microbiology are under the categories of pure and applied sciences.
But, what are some of the techniques and methods of microbiology that scientists explore more carefully? The following are a few techniques:
- Negative and Simple Stains,
- Staining for Electron Microscopy,
- Physiological Techniques,
By taking a more specific look at any of the previously mentioned methods, you will acquire a more thorough understanding of how microbiology works and how essential it is. Since the 19th century, scientific microbiology has made many cleaning techniques possible that keep us safe and far away from harmful diseases.
In conclusion, by analysing the methods of molecular biology, biochemistry, microscopy, and microbiology, we have a better idea about how their techniques are similar to the characteristics of experimental biology. Furthermore, by studying biology, we develop a more sincere appreciation for our giant blue planet, something we should all strive to do!
