Imagine that DNA is composed of equal proportions of six different types of nucleotide, instead of the normal four.The six nucleotides are A, C, G, T, X, and Y.In this new type of DNA molecule, A pairs with T, C pairs with G, and X pairs with Y.What would be the average size of the DNA fragments produced when this new DNA is cut by a restriction endonuclease with a four-base recognition sequence?
