What is Biophysics?

Protien Translation Biophysics takes fundamental physics concepts and applies them to understand how biological systems work. Biophysicists take a much more quantitative approach, looking at the data and calculations behind all of the experiments. This leads to much of the work being completed in labs with a focus on genetics and cells as opposed to animals and plants. Despite not being mentioned by name, chemistry is also a necessity why working in Biophysics. Much of the application of physics occurs when studying the various molecules present in many organisms and cells. This can include looking at the biomolecules related to many disease such as Alzheimer’s disease, ALS (“Lou Gehrig’s disease”), HIV, diabetes, breast cancer, and multiple sclerosis.

Protein Translation

To the right you see an animation representing the process of protein translation that sees mRNA telling ribosomes within a cell what amino acids they should use to build a protein. The mRNA is read by the ribosome and translated into these long chains of amino acid that become protiens. These protiens are then used to build up the structure in your body, such as the heart or lungs.

Kinesin

Another example of how biophysics can be applied is with the protien kinesin. It belongs to a class of motor protiens that move along the cytoplasm of eukariotic cells. Kinesins are powered by ATP(Adenosine triphosphate) to walk along microtublue filiments to deliver cargo during functions such as meiosis and mitosis.
