Rose in Peterborough asked:
How many different types of DNA can you get?
There are two answers to this question. One is that there is only a single type of DNA, as it's all made up of the same basic codes. However, there are certain sub-types of DNA. These include cDNA, which stands for coding DNA, and single stranded DNA, which looks like a ladder cut in half.
