to determine the phylogeny of organisms. Discuss one strength of each type of evidence you
-comparison of phenotypes: bone structures, homologous and analogous structures, show
similarities in DNA
-DNA sequence: a look at the genome nucleotide sequence can show similarities in
organisms; can look at specific genes !
! -prions are misfolded versions of normal brain protein
-ON AP TEST-Which of the three types of viruses shown above would you expect to include
glycoproteins: (the little pinheads=glycoproteins)
-round ones; not the bacteriophage with the legs and heard
