(c) Describe TWO types of evidence—other than the comparison of proteins—that can be used to determine the phylogeny of organisms. Discuss one strength of each type of evidence you described. -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 -Which of these statements about prokaryotes is correct? -they divide by binary fission, without mitosis or meiosis -Foods can be preserved in many ways by slowing or preventing bacterial growth. Which of these methods should be least effective at inhibiting bacterial growth? -closing previously opened containers: prevents more bacteria from entering, and excludes O2 -Which associated with "mad cow disease": -a prion -prokaryotes don't have nucleus: so they don't need meiosis or mitosis...
