The initial ‘unzipping’ stage is carried out by DNA helicase, to create a fork of DNA with exposed base pairs. DNA helicase works by breaking the hydrogen bonds between b...
A good answer would start with a definition of a synapse ('the junction between two neurones') and then be formatted as bullet points or numbers for clarity and backed up with a diagram.Action pot...
