Document Summary
Biology 207 - practice questions 1 - answers. Question 1 suppose one was provided with an actively dividing culture of e. coli bacteria to which radioactive thymine had been added. What would happen if a cell replicated once in the presence of this radioactive base: dna in both daughter cells would be radioactive. Question 2 the chromosome of e. coli o157:h7 is 5 498 450 bp long and has a g+c content of 52%. If g+c is 52% then the relative amount of g must be 26%, c is 26%, a is 24%, and t is 24%. This chromosome contains 10 996 900 nucleotides of which approximately 2 859 194 are g, 2 859 194 are c, 2 639 256 are a, and 2 639 256 are t. Question 3 explain why each of my rules governing nucleic acid synthesis holds true for the process of dna replication.
