DNA Paternity Testing: How Do Labs Do It?

People are taking more and more to DNA testing these days. And in an age where anything can be stolen from bags, cars to identities, DNA testing has provided us with an accurate identification system that cannot be denied or lied about. As they say, it’s all in the genes!

DNA Molecules

Deoxyribonucleic acid, or DNA, is the component containing the blueprint that specifies the biological development and composition of every form of life. Its general structure is in the form of a double helix and is primarily made up of nucleic acids. DNA is a polymer strand of nucleotides that contain sequences using genetic codes. For most complex cells, DNA is actually located in the cell nucleus. The physical model of the DNA molecule has always been a source of great mystery to a lot of people. How can a tiny molecule be responsible for carrying all genetic information?

Voltage Transformers

In order to switch on electrical equipment we need the mains supply which either provides us with an output of 110 Volts or 220 Volts of Alternating Current (AC). The question here is what the compatible voltage for the equipment is. If you find that your supply is 110 Volts and the equipment requires 220 Volts AC, you need a step-up voltage transformer to run that equipment. If it is the other way round, a setp-down voltage transformer would be required.
