If DNA inside a cell is damaged, a protein called p53 halts the cell cycle. With this in mind, explain how a p53 gene mutation could cause cancer to develop.

Cancer cells have damaged or mutated DNA. If p53 was functioning, it would stop the cell cycle and ensure damaged cells did not multiply. However, if the gene coding for p53 is faulty, cell division would...

Integrate y=(x^2)cos(x) with respect to x.

This problem must be solved using integration by parts, since y is equal to the product of two functions of x. Let u=x^2, therefore u'=2x (u'=du/dx). Let v'=cos(x), therefore v=sin(x) (v'=dv/dx).Using the...

The enthalpy change for the forward reaction is -92kJ/mol. State and explain how the value of Kp would change if the temperature was increased.

The value of Kp would decrease.Using Le Chatelier's principle the position of equilibrium would shift so as to oppose the change.The endothermic (backward) reaction would therefore be favoured in order to...
