- REFLECT AND APPLY In the MeselsonStahl experiment that established the semiconservative nature of DNA replication, the extraction method produced short fragments of DNA. What sort of results might have been obtained with longer pieces of DNA?arrow_forwardREFLECT AND APPLY Suggest a reason why it would be unlikely for replication to take place without unwinding the DNA helix.arrow_forwardREFLECT AND APPLY What difficulties arise in the polymerase chain reaction if there is contamination of the DNA that is to be copied?arrow_forward
- REFLECT AND APPLY What is the complete base composition of a double-stranded eukaryotic DNA that contains 22% guanine?arrow_forwardREFLECT AND APPLY E. coli incorporates deoxyribonucleotides into DNA at a rate of 250 to 1000 bases per second. Using the higher value, translate this into typing speed in words per minute. (Assume five characters per word, using the typing analogy from Question 36.)arrow_forwardREFLECT AND APPLY Your book contains about 2 million characters (letters, spaces, and punctuation marks). If you could type with the accuracy with which the prokaryote E. coli incorporates, proofreads, and repairs bases in replication (about one uncorrected error in 109to1010 bases), how many such books would you have to type before an uncorrected error is permitted? (Assume that the error rate is one in 1010 bases.)arrow_forward

- REFLECT AND APPLY Explain how DNA gyrase works.arrow_forwardREFLECT AND APPLY A technology called PCR is used for replicating large quantities of DNA in forensic science (Chapter 13). With this technique, DNA is separated by heating with an automated system. Why is information about the DNA sequence needed to use this technique?arrow_forwardREFLECT AND APPLY Mitochondria and chloroplasts contain some DNA, which more closely resembles prokaryotic DNA than (eukaryotic) nuclear DNA. Use this information to suggest how eukaryotes may have originated.arrow_forward
