Quiz: A Basic Questions On DNA!

All cells and some viruses contain DNA and this is a nucleic acid that contains the genetic instructions for the development and function of living things. DNA profiling is especially useful for solving crimes but can also be used to confirm if people are related to each other, such as for paternity testing. Test your knowledge on DNA basics by taking up the test below.
