If a mutation that inactivated telomease occurred in a cell (telomerase activity in the cell 5 zero) what do you expect the outcome to be? 27. On the planet of Rama, the DNA is of six nucleotide types: A, B, C, D, E, and F. A and B are called marzines, C and D are orsines, and E and F are pirines. The following rules are valid in all Raman DNAs: Total marzines 5 total orsines 5 total pirines A 5 C 5 E B 5 D 5 F a. Prepare a model for the structure of Raman DNA.

Unformatted text preview: b. On Rama, mitosis produces three daughter cells. Bearing this fact in mind, propose a replication pat-tern for your DNA model. c. Consider the process of meiosis on Rama. What comments or conclusions can you suggest? 28. If you extract the DNA of the coliphage f X174, you will find that its composition is 25 percent A, 33 per-cent T, 24 percent G, and 18 percent C? Does this composition make sense in regard to Chargaffs rules? How would you interpret this result? How might such a phage replicate its DNA?...
