Is it something related to the equation for ideal gas? but in pV = nRT, the "n" has changed cos in 43.0 C water is liq but vapor is gas. Sorry, I've got no idea about it since I'm doing biology...
I'm really confused, cos I've learned that the distance from the well measured should be proportional to the log10 value of the DNA size. And by theory I should have got a straight line or nearly straight, but the curve I've got doesn't seem to be straight at all!
Hi everyone, I ran a gel for restriction digestion and used lamda HindIII as the marker. When I'm drawing the graph on a semi-log paper, size on y-axis and distance from the well on the x axis, the standard curve isn't a straight line, but a linear curve. Is it fine?
Another question: the...
I'm writing an essay on comparing 5 sensory systems, and have been looking at the chapter of sensory systems in Stryer's "biochemistry" textbook.
It is really confusing me because I've just seen a "totally unknown" on hearing and touch :bugeye: , and i want to look at journals on the 5...
I'm quite confused about the minimal growth requirements for different auxotroph E.coli cells. How can I deduce the minimal conditions for these? e.g.
E.coli leu trp val bio
E.coli leu(am) trp(ts) supF
E.coli ilv trp leu(am) supF(ts)/F'val
E.coli delta(ara-leu) (lamda cI(ts))
Could anyone help me make sense of the foundations and procedures of the soxhlet extraction. I've got absolutely no idea about this and going to do this experiment tomorrow...
Thanks very much!
Why does a racemic mixture of 98:2 enantiomers consist of one enantiomer in 96% over the other? I'm still not clear about this after reading textbooks. And how about the other one? does it have a negative percentage value of enantiomeric excess?
I'm a foreign student in England studying biochemistry, 1st year undergraduate. I did an experiment yesterday on infrared spectrum and was confused by the output diagram. I also don't know about how it works. Could anyone tell me how do I look and analyse the infrared spectrum diagram and what...
Modern society has tended to adopt a more liberal attitude towards homosexuality. To what extent do you think this trend is damaging to traditional concepts of ¡®family¡¯?
