There are many enzymes which are crucial for replication. The first is helicase which unwinds the double helix at the replication fork. DNA gyrase then reduces the strain caused by the unwinding of the helix...

When an action potential from a pre-synaptic neuron approaches a synapse, the change in membrane potential causes voltage-gated calcium ion channels to open across the pre-synaptic bulb. Due to the high diff...

ADH is a hormone that decreases the urine output in humans. It is produced by the hypothalamus and secreted by the posterior pituitary gland. The production is controlled by osmoreceptors and baroreceptors i...

The cell membrane consists of a mosaic of proteins and a phospholipid bilayer, with the hydrophobic fatty acid tails orientated inwards and the hydrophilic phosphate heads outwards. The main function is to c...

DNA is a double stranded construct of genetic information with nucleotides: Adenine, thymine, guanine, and cytosine. DNA contains deoxyribose. mRNA is a single stranded transcribed version of a DNA sequence ...
