Document Summary

Xyy normal intelligence very small testes sterile short statue. Webbed neck shield-like chest internal sex organs do not mature. Avery macleod mccarty experiment, 1944 (cid:224: heat killed s strain, bc of macromolecules remove lipids and carbos, add enzyme to digest one type of macromolecule, digest protein (cid:224) leaves dna and rna = transformation, digest rna (cid:224) leaves dna and protein = transformation, digest dna (cid:224) leaves protein and rna = no transformation transformation requires dna to be present. Hersey chase exp, 1952 (cid:224: grow viruses in radioactive 35s, which is in protein to attach to protein coats, grow viruses in radioactive 32p, which is in dna to attach to inner dna molecule. from the cells, allow them to infect e. coli and then agitate bacteria to remove the protein coats, centrifuge solutions to force cells into a pellet, measure and note where the radioactivity is in the test tubes.
