A mutation is a change in the DNA base sequence. This causes a change in the amino acid that is synthesised, and this could change the shape of the active site on an enzyme. The shape of the active site m...

Using the quotient rule: Let u=x and v=2x+5 then du/dx= 1 and dv/dx=2 Hence dy/dx=[(2x+5)x1- (2x)]/(2x+5)²             =5/(2x+5)²

DNA is a double-stranded nucleic acid that consists of four different bases (A, T, C, G) which make up the 'language' of the genome. Sets of three bases on the coding strand of DNA, known as a triplet cod...

First, you must find out the total amount to pay back, this amount will be £720 + 15% of £720. To find 15% of £720, we first calculate 720/100 to find 1% and the multiply by 15: 720/100 = 7.2 *15 = 108. N...

Draw argand diagram

Modulus=|z|= length of the line

So |z|=(x²+y²)^0.5

Argument=Angle between real (x axis) and line

so arg(z)=arctan(y/x)
