DNA And RNA Structure Test Quiz!

What are DNA and RNA? DNA and RNA are the most essential molecules in cell biology. They help with keeping and reading genetic information that exemplifies all life. They are both linear polymers, consisting of sugars, phosphates, and bases. DNA provides the code for a cell’s activities, while RNA translates it into proteins to carry out cellular functions. You must take this quiz on DNA and RNA and learn interesting trivia in the most fun way.
