Biology Question?
D





The rest are all the number 3
Reply:eh, there are actually 4 kinds of RNA; mRNA, tRNA, rRNA and snRNA, but you probably havent talked about snRNA. I'm not exactly sure what you mean by "number of types of DNA." If it means the A form, B form and Z form, then there would be 3 types of DNA.





So I guess the answer depends on if you have talked about snRNA and what you mean by "types of DNA"
