Greetings all, I have a problem where I am asked to estimate the number of DNA polymerase in a eukaryotic cell. The sub-question prior to this asked me to find what fraction of the total DNA of a fly was shown in a micrograph in my book. How do I go about estimating this? Is it 2 for each...

Hi there I'm a biochemistry major third year because I'm interested in biology but wanted to have a firm grounding in the physical sciences. Admittingly, the grounding is rather superficial with biochemistry which is why I am trying to supplement with as many physical science and math classes as...

My school does not have a "biophysics" major and I wanted to major in biophysics as that is a field I want to head into. With only about 8 more classes to complete a major in physics (from PSEO to college courses, I took more physics classes than not), should I just tack that on with my biology...

The second question from the attachment. Since I couldn't attend the lectures, I have difficulties in solving the problem.. If you give some hint, or guidance to me, i will be happy..

Hi all, I am a current physics undergrad student. I recently got a position on a research team doing several different biophysics research projects. Since I am just an undergrad, I get to start out doing basic low-level work like running image analysis algorithms. I am getting a little...

Im currently a senior at a large state university (LSU), and have been studying economics(major) and math(minor) and have a 4.0 so far. Recently i decided i did not want to pursue economics, and became much more drawn to the pure sciences. I decided to stay in school and study physics and bump...

I have been given an assignment to find out about the applications of modern biophysics in tissue engineering ! I just need a little background on how biophysics and tissue engineering are inter-related (if they are). I just had an idea that they might be something about some tissue...

Hi everyone! Short-time lurker here, and I have a fairly important question that I'd like some input on. I'll keep it simple, but I do have a lot of related questions so I may branch out as the thread goes on. I am considering getting a physics phd with a focus in biophysics. In particular...
