Question

How would the DNA of a fish compare to the DNA of a lion?

Answer 1

DNA comparison can be done by using DNA hybridization or by analyzing sequences which mainly involves subjecting a DNA, RNA or peptide sequence to any of a wide range of analytical methods to understand its function, features, evolution, or structure. Plenty of housekeeping genes can be found in common because they are animals, either chordates, vertabrates or eukaryotes.
