Prototype polymerase chain reaction (PCR) machine
The nickname of this machine is ‘Baby Blue’. The Baby Blue prototype was devised in 1986 to replicate DNA from a tiny sample. Samples would be used to study HIV and genetics. The double helix structure was separated by heating each strand. A mating strand was then created with the help of a special enzyme which can stand high temperatures, forming new double helixes. This process was repeated 25-35 times. This is the first model which combines the software controlling the process with the heating and cooling block in one machine.
