When an action potential reaches the synaptic knob of the pre synaptic neurone, this causes calcium ion channels to open. This leads to an influx of calcium ions ( Ca2+) into the synaptic knob. Presence o...

Similarities: both encode genetic information; both can bind nitrogenous bases adenine, guanine and cytosine; both are polar and have a 5' end and a 3' endDifferences: RNA binds uracil, whereas DNA binds ...

The active site of the enzyme has a specific active site that is complementary to maltose. This means that maltose can only bind to maltase to form an enzyme-substrate complex.

The transmembrane protein transport a molecule against the concentration by active transport (1) which requires ATP (1).

The process of DNA replication involves unwinding the original DNA strand by the enzyme DNA helicase. This enzyme breaks the hydrogen bonds between complimentary bases forming two single ...
