Classification using DNA or proteins Flashcards
How is genome sequencing used to clarify evolutionary relationships?
The DNA base sequence of one organism can then be compared to the DNA base sequence of another organism to see how closely related they are
What will closely related species DNA look like?
They would have a higher percentage of similarity in their DNA base sequence
How can comparing amino acid sequences be used to clarify evolutionary relationships?
The sequence of amino acids in a protein is coded for by the base sequence in DNA
What will closely related organisms amino acid sequences look like?
Related organisms have similar DNA sequences and therefore similar amino acid sequences in their proteins
How can immunological comparisons be used to clarify evolutionary relationships?
Similar proteins will also bind the same antibodies
