Single-stranded regions of DNA are attacked by nucleases in the cell, yet portions of DNA are in a singlestranded form during the replication process. Explain.
A student has drawn an enlarged portion of a DNA “ladder” model to show two of the nucleotides in greater detail (in the same orientation as they would occur in the ladder model). Which two nucleotides did the student draw?
Suppose a future scientist explores a distant planet and discovers a novel form of double-stranded nucleic acid. When this nucleic acid is exposed to DNA polymerases from E. coli, replication takes place continuously on both strands. What conclusion can you draw about the structure of this novel nucleic acid?

- If DNA replication followed the dispersive model of replication, how would the outcomes of the Meselson-Stahl experiment change? Describe the composition of DNA samples after one and two rounds of replication, and how this is different from the findings of the original experiment.arrow_forwardWhen Chargaff was performing his experiments, the tetranucleotide hypothesis, which stated that DNA was composed of GACT nucleotide repeats, was the most widely accepted view of DNA’s composition. How did Chargaff disprove this hypothesis?arrow_forwardSuppose the gaps between the Okazaki fragments are not sealed and a continuous strand does not form. You could conclude that this is due to a mutation for which enzyme? DNA polymerase DNA helicase DNA ligase RNA primasearrow_forward
