Hi all, I have been reading some papers where they talk about RNA transcription rates in operons namely lac and unc. Can anyone tell me how does one go about in calculation of these rates? Thanks, Nancy

Hi, I was wondering if given the concentration of DNA, how does one calculate the concentration of nucleotides? Are they the same thing? Thanks. Nancy

Hi pmsrw3, Yes I am rotating a line about one point. I translate all the line segments that I am studying to the origin. I want to rotate all the lines so that they fall on the positive X axis. I am using MATLAB. So I need to determine the correct angle for rotation, if not I get segments on...

Hi Guys, I want to rotate a line so that it lies on the positive x direction. I can determine the equation of the line as y=m*x+c where m is the slope and c is the intercept. The angle of rotation, theta is known by tan inverse of m. Now theta can be either -theta or -(pi+theta) depending on...

Can anyone tell me why are Concanavalin A coated dishes used in cell imaging? Nancy

Ryan, I didn't understand what you meant by treating a polymer statically. Thanks Ygggdrasil. That definitely cleared things. I was also wondering what will be the behavior of the cord in the following cases. 1. Its length is lower than the persistence length. 2. Its length is higher than...

Thanks Ryan. Could you further elaborate on that?

I was reading an article which talked about measuring the persistence length of DNA and microtubules. I didnt understand what the term meant, tried wikipedia but it confused me further. So could anyone explain what persistence length means in layman terms? Nancy
