1) When Meselson and Stahl grew Escherichia coli in 15N medium for many generations and thentransferred the cells to 14N medium for one generation, they found that the bacterial DNA banded ata density intermediate between that of pure 15N DNA and pure 14N DNA following equilibrium densitycentrifugation. When they allowed the bacteria to replicate one additional time in 14N medium, theyobserved that half of the DNA remained at the intermediate density, while the other half banded atthe density of pure 14N DNA. What would they have seen after an additional generation of growth in14N medium? After two additional generations? 2) Draw a diagram of replication that is occurring at the end of a double-stranded linear chromosome.Show the leading and lagging strands with their primers (indicate the 5′ and 3′ ends of the strands).What difficulty is encountered in producing copies of both DNA strands at the end of a chromosome?

Price et al. [(1999). J. Bacteriol. 181:2358–2362] conducteda genetic study of the toxin transport protein (PA) of Bacillusanthracis, the bacterium that causes anthrax in humans. Withinthe 2294-nucleotide gene in 26 strains they identified five pointmutations—two missense and three synonyms—among differentisolates. Necropsy samples from an anthrax outbreak in 1979revealed a novel missense mutation and five unique nucleotidechanges among ten victims. The authors concluded that thesedata indicate little or no horizontal transfer between differentB. anthracis strains. Question: Which types of nucleotide changes (missense or synonyms)cause amino acid changes?
