principle of error-prone PCR???

Thanks so much for your answer. But how exactly the size of Mn ions affect the Taq enzyme? Did they changes the fourth-level structure of the Taq enzyme, such as combine with the regulatory subunit to control the activity, or something else. I mean, it ...

principle of error-prone PCR???

Hello guys, recently I was told by a classmate that Mn2+ ions is the key of error-prone PCR. I checked on the internet and I got nothing. I always thought the low-fidelity PCR enzyme is the reason leading to the error matches of basicpair. I am now confused, ...

Too many ions inside a neuron cell. What happens?

... where the sodium channel cannot gauge voltage difference effectively, and so it remains open, rapidly building up a concentration of sodium ions in the cell, and this disorder often affects potassium channels, so there is practically no way that the excess sodium ions can escape as they ...

Re: Are carbohydrates hydrophobic?

... (2)). The polarity of water makes it a “universal solvent”. Its components have a slight electrical charge that makes possible the dissolution of ions. Many authors state that if water didn’t have its properties, many of the artificial and natural reactions wouldn’t be possible. References: • ...
