First-order reaction

First-order reaction

a reaction the rate of which is proportional to the concentration of the single substance undergoing change; radioactive decay is a first-order process, defined by the equation -(dN/dt)=kN, where N is the number of atoms subject to decay (reaction), t is time, and k is the first-order decay (reaction) constant, i.e., the fraction of all atoms decaying per unit of time.

See: decay constant, order.

Ligase reaction problem

Dear Friends, I uploded an image you can see below. Here, I want to ask whether it is enough base lenght for ligase reaction via thermostable ligase in 63 C (Protocol: 5 cycle at 95 C-30 s and 63 C-4 min) I think I take cross reaction because of this dimer but I am not sure. Is it ...

Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... thank you! I have wondered for a while what drives protein synthesis forward in terms of energy, and why don't ribosomes also catalyse the reverse reaction of peptide formation, now I guess it's due to the GTP hydrolysis? But I also have some questions about the above post, maybe someone can help ...

Morgellons cure

I found the real cause of suffering skin. Morgellons has no cure. Morgellons is a cure. More specifically it is a normal reaction to some extremely dangerous factors. I have tested and confirmed two-way relationship between cause and effect. Morgellons is a warning. Perhaps the last ...

Gateway technology

... material with bacterias. However, why do I need to perform the BP reaction, if I want to obtain an expression clone of a certain gene? Why ... clone attB in the end? I can't understand why we have to perform the first reaction! Help!

Re: An interesting PCR smearing...I dont know what to do :(

... well ( a single bright band ) but the other two exon amplification is not coming properly.and this has occured recently. ( even though the PCR reaction was standardized earlier ) I have used same reagents , pipettes , PCR machine , reconstituted new primers for amplifying all 3 exons . Interestingly ...
