1. If a strand is given to you, and you have to identify whether it is DNA or RNA how will you identify it?
pickupchik [31]
One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
