DNA: The Molecule Of Life! Trivia Quiz

DNA is the genomic material in cells that contains the genetic information used in the development and functioning of all known living organisms. DNA is essential for life. It is responsible for the storage and reading of genetic information. DNA is protected by proteins and has several repair mechanisms. It is a double-stranded molecule that forms a double helix. This quiz is all about DNA. Don't worry, you can do it. Just go for it.
