Chapter 9, Problem 8P
The linear bacteriophage λ genomic DNA has at each end a single-strand extension of 20 bases. (These are sticky ends but are not, in this case, produced by restriction enzyme digestion.) These sticky ends can be ligated to form a circular piece of λ DNA. In a series of separate tubes, either the linear or circular forms of the DNA are digested to completion with EcoRI, BamHI, or a mixture of the two enzymes. The results are shown here.
| a. | Which of a. the samples (A or B) represents the circular form of the DNA molecule? How do you know? |
| b. | What is the total length of the linear form of the λ DNA molecule? |
| c. | What is the total length of the circular form of the λ DNA molecule? |
| d. | Draw diagrams of the circular and linear λ DNA molecules, showing the locations of the EcoRI and BamHI sites. |

- Given the following double-stranded fragment of DNA: 5'- ACTTGGCAGGCCTTCGATCC-3' 3'- TGAАССGTCСGGAAGCTAGG-5' A hypothetical restriction endonuclease recognizes a 6bp sequence with two-fold symmetry (typical for restriction enzymes) found in this fragment and catalyzes cleavage of this DNA on both strands between GG nucleotides within the recognition sequence. This nuclease exhibits b-type cleavage (atypical for restriction enzymes). Draw the double-stranded sequence of each fragment after cleavage showing any phosphates left on the ends.arrow_forwardWhen circular DNA is sequenced, the nucleotide base pairs are numbered starting from a fixed position on the DNA, all the way around, usually in a clockwise manner. a DNA molecule that is 3133 base pairs long is digested with RsaI restriction enzyme recognition sites at base numbers 366, 1534, and 2207. What are the sizes of the DNA fragments that will be produced after the DNA is digested with RsaI?arrow_forwardYou are studying a protein that contains the peptide sequence RDGSWKLVI. The part of the DNA encoding this peptide is included in the sequence shown below. 5'-CGTGACGGCTCGTGGAAGCTAGTCATC-3' 3'-GCACTGCCGAGCACCTTCGATCAGTAG-5' This sequence does not contain any BamHI restriction enzyme sites. The target sequence for the BamHI restriction nuclease is GGATCC. Your goal is to create a BamHI site on this plasmid by manipulating the DNA sequence, without changing the coding sequence of the protein. How would you do this, ie what would the new sequence be?arrow_forward
- All are correct about DNA gyrase in E. coli EXCEPT: It works to remove positive supercoiling introduced by the DnaB protein (helicase). It is a topoisomerase that hydrolyzes ATP during its reaction mechanism. Its mechanism involves the breaking of a single phosphoester bond in one strand of dsDNA. It works to relieve supercoiling in DNA to overcome the torsion stress imposed upon unwinding.arrow_forwardThe partial sequence of one strand of a double-stranded DNA molecule is 5'-GACGAAGTGCTGCAGAAAGTCCGCGTTATAGGCATGAATTCCTGAGG -3' EcoRI is a restriction enzyme that cleaves after G in the sequence 5'-GAATTC-3'. PstI is a restriction enzyme that cleaves after A in the sequence 5'-CTGCAG-3'. Write the sequence of both strands of the DNA fragment created when this DNA is cleaved with both EcoRI and PstI. The first strand of your duplex DNA fragment should be derived from the given strand sequence. 5'- -3' 3'- -5'arrow_forwardThe restriction endonuclease BamHI recognizes the sequence GGATCC and cleaves between the Gs (in both strands). The enzyme Bgl II recognizes AGATCT and cuts between AG (in both strands). Justify your answers. 1. Draw the double stranded sequences of the DNA pieces shown above and indicate with an arrow the cutting points for each of the enzymes. Use different two colors for the two different sequences (one color for BamHI and another one for BglII). Do they generate blunt ends or sticky ends? 2. Draw the two sequences arising from each the cut (there will be four sequences).arrow_forward
- Restriction endonucleases are bacterial enzymes that cleave duplex (double-stranded) DNA at specific nucleotide sequences. The mode of replication of the animal virus SV40 has been investigated by using restriction endonucleases that cleave SV40 DNA into a number of unique segments. Like most viruses, SV40 DNA is circular. The map positions of the 11 fragments produced by a pair of restriction endonucleases are shown on the next page. Immediately following a 5 or 10 minute pulse of radioactively labeled thymidine, labeled SV40 molecules that have completed replication during the pulse are isolated. These newly replicated DNA molecules are digested by the restriction endonucleases and the resulting fragments are analyzed for the relative amounts of pulse label they contain. The results are in the table below. Assume that at the time the label was added there was a random population of replicating SV40 DNA molecules in all possible stages of synthesis. From the information given below,…arrow_forwardWhat, if any, are potential restriction enzyme recognition sequences in this DNA? (Only consider sequences of 6 bp or longer.) Using any of the sites which you identified in above, illustrate cleavage positions for that site which will result in a 5’ overhang or a 3’ overhang respectively.arrow_forwardA linear piece of DNA that is 14 kb long is cut first by EcoRI alone, then by SmaI alone, and finally, by both EcoRI and SmaI together. The following results are obtained: Draw a map of the EcoRI and SmaI restriction sites on this 14-kb piece of DNA, indicating the relative positions of the restriction sites and the distances between them.arrow_forward
- In each case, if 1 µg of DNA was digested by these enzymes, calculate the number of ng of DNA present in each fragment (complete the table).arrow_forwardEven though the eukaryotic genome is thousands of times larger than the prokaryotic genome, DNA replication times are relatively similar. Explain how this is possible.arrow_forwardHow often, on average, would you expect a type II restriction endonuclease to cut a DNA molecule if the recognition sequence for the enzyme had 5 bp? (Assume that the four types of bases are equally likely to be found in the DNA and that the bases in a recognition sequence are independent.) How often would the endonuclease cut the DNA if the recognition sequence had 8 bp?arrow_forward
