DNA helicase unwinds the DNA double strand / causing hydrogen bonds between complimentary base pairs to break / both single strands used as templates / DNA replication is semi conservative and semi discon...

The easiest way to solve this is to split the fraction into partials.Using partial fractions, we get A/(x-3)+B/x=x+3/(x(x-3)) implies Ax+B(x-3)=x+3We want to find the values of A and B that solve this, so...

All three molecules have induced dipole-dipole interactions. Propane has a higher boiling point than ethane as propane has a higher molecular mass. This means there are more electrons present and the indu...

The stationary points are located where the gradient of the function is equal to 0. The first derivative of the function describes the gradient so we must differentiate the function to find dy/dx.
U...

To start, we need to know that the gradient of the curve at the stationary points is 0 and that when the second derivative is less than 0, there is a maximum and when the derivative is greater than 0, the...
