Hello, and welcome to this MCQ on RNA blog! In this MCQ on RNA post, we’ll ask you a few questions about RNA to see how much you know about it (MCQs). RNA is a very interesting molecule that is a key part of how genes are turned on and off and how proteins are made. It is a single-stranded nucleic acid that is needed for DNA to send genetic information to ribosomes, which make proteins. How much do you know about RNA?
