Genomes, Transcriptomes And Proteomes! Trivia Questions Quiz

The cell is the building block for living things, and they have different purposes that they serve within the body. The genes in the human body are contained in a cell and act as markers for specific attributes. The quiz below is perfect for a medical student who has just covered genomes, transcriptomes, and proteomes, is that you? Well, take it up and get a better understanding of the subjects.
