01: If all genes are composed of just four nucleotides, how can different genes carry different types of information? 02: Would you expect to see more variation in the sequence of DNA bases between two members of the same species (such as humans) or between two individuals of different species (for example, humans and chickens)? Explain your reasoning. Q3: Do different alleles of a gene have the same DNA sequence or different DNA sequences?
