Similarity between DNA sequences of two eukaryotic species is used to predict their evolutionary relatedness, pointing to a shared ancestry. In an attempt to evaluate this relatedness, a group of researchers sequenced and compared two proteins with the same function from the two species. The corresponding DNA and RNA sequences were also compared to decipher their relatedness. Based on this information, the correct op

Options

  1. ASimilarity in exons, but not necessarily in introns, is reflective of divergent evolution.
  2. BSimilarity in the protein sequence, but not in the corresponding RNA or DNA sequence can be an example of dive
  3. CSimilarity in introns, but not in exons, is reflective of convergent evolution.
  4. DThough the overall protein sequences are not similar, the conservation of active site residues cannot be due t
