What we have here is a trivia quiz on molecular biology of DNA replication! The DNA of a human can copy itself and this is one of the reasons why people of the same bloodline can be identified using a DNA test. Do you know the processes through which the DNA actually duplicates itself and the results there after? This quiz will serve as a way to refresh your memory.
