DNA Quizzes & Trivia

Transcription is the process by which DNA is copied to mRNA, which carries the information needed for protein synthesis. We got to cover the whole process in class this past week. If you like answering specifically designed questions that the future or specific information about transcription and translation try out this quiz. It is a simple quiz; therefore, it will be easy to answer.
