Textbook Question
Chapter 10, Problem 20PDQ
Several temperature-sensitive mutant strains of E. coli display
the following characteristics. Predict what enzyme or function is
being affected by each mutation.
(a) Newly synthesized DNA contains many mismatched base pairs.
(b) Okazaki fragments accumulate, and DNA synthesis is never completed.
(c) No initiation occurs.
(d) Synthesis is very slow.
(e) Supercoiled strands remain after replication, which is never completed.

In a DNA double helix, why doesn't an A or T form two hydrogen bonds (out of the three possible ) with G or C? Explain how DNA replication is bidirectional and discontinuous in nature?
Provide a chemical explanation of why DNA synthesis proceeds in a 5'- to-3' direction.
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?

- Replication involves a period of time during which DNA is particularly susceptible to the introduction of mutations. If nucleotides can be incorporated into DNA at a rate of 20 nucleotides/second and the human genome contains 3 billion nucleotides, how long will replication take? How is this time reduced so that replication can take place in a few hours?arrow_forwardDNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?arrow_forwardWhy is DNA replication called semiconservative?arrow_forward
- Given the following DNA sequence: 5’-ATGCGGCCAAGGTCAGAGTGACA-3’ a) If this DNA strand represents the “Sense Strand” of DNA, what would be the RNA sequence? b) If this DNA strand represents the “Antisense Strand” of DNA, what would be the RNA Sequence? c) What would be the other strand of DNA?arrow_forwardAfter Alfred Hersey and Martha Chase definitively identified DNA as the “Transformative material”, which three scientists were responsible for characterizing the structure of DNA? How did they do it?arrow_forwardWhy do we say that DNA replication is semiconservative?arrow_forward
- If DNA synthesis occurs without error, the resulting double-stranded DNA is an exact copy of the original double-stranded DNA (exact in that the base sequences are identical). Does this mean then that in DNA synthesis, the two single-stranded templates are identical? Explain.arrow_forwardIn terms of the new DNA strands that are generated, what are the differences between replication and conventional polymerase chain reaction?arrow_forwardThe double helical structure of DNA is intrinsically unstable and easily dissociates to form two separate strands. Why? How does this affect the two key biological functions of chromosomal DNA? What would happen if the DNA helices were too stable?arrow_forward
