The genоme оf а mutаnt strаin оf E. coli (that does not naturally contain EcoRI) has two recognition sequences for EcoRI. The same sequence is also found once in a plasmid of the same strain. More specifically, the recognition sequences in the bacterial chromosome are flanking the operator of the lac operon, while the recognition sequence in the plasmid is found downstream of the promoter of the streptomycin resistance gene. In your experiment, you introduce EcoRI in this strain, and it cleaves all the recognition sequences. Following ligation, the bacteria contain a circular chromosome and a plasmid that contains the operator sequence. a. How many phosphodiester bonds were there cleaved by EcoRI? b. What do you predict the result will be when this strain is streaked in a petri dish in the presence of glucose and streptomycin? c. What do you predict the result will be when this strain is streaked in a petri dish in the presence of lactose and streptomycin?
DNA cоmplementаry tо pepper mRNA wаs synthesized using оligo (dT) аs a primer for first strand synthesis. The second strand (synonymous with the mRNA) was then synthesized, and the population of double stranded cDNAs were ligated into a plasmid vector using a procedure that leaves PstI sites flanking the cDNA insert (i.e. the terminal PstI sites for each clone are not part of the cDNA). This cDNA library was screened for clones made from the mRNA from the pepper yellow gene. One clone was isolated, and subsequent analysis of the pattern of restriction endonuclease cleavage patterns showed it had the following structure: The map shows the positions of restriction endonuclease cleavage sites and the distance between them in kilobases (kb). The map of the cDNA insert is shown with solid lines, and plasmid vector DNA flanking the cDNA is shown as dotted lines. The top strand is oriented 5' to 3' from left to right, and the bottom strand is oriented 5' to 3' from right to left. The positions and orientations of two oligonucleotides to prime synthesis for sequence determination are shown and are placed adjacent to the strand that will be synthesized in the sequencing reaction. Oligonucleotides that anneal to the plasmid vector sequences that flank the duplex cDNA insert were used to prime synthesis of DNA for sequencing by the Sanger dideoxynucleotide method. A primer that annealed to the vector sequences to the left of the map shown above generated the sequencing gel pattern shown below on the left. A primer that annealed to the vector sequences to the right of the map shown above generated the sequencing gel pattern shown below on the right. The gels were run from the negative electrode at the top to the positive electrode at the bottom, and the segment presented is past the PstI site (i.e. do not look for a PstI recognition site). a. What is the DNA sequence of the left and right ends of the insert in the cDNA clone? Be sure to specify the 5' to 3' orientation. The terms left, right, top and bottom all refer to the map shown above for the cDNA clone. The sequence of the left end of the top strand is [blank1] and the sequence of the right end of the bottom strand is [blank2] b. Which end of the cDNA clone (left or right in the map above) is most likely to include the sequence synonymous with the 3' end of the mRNA? [blank3] c. What restriction endonuclease cleavage sites do you see in the sequencing data given? (Write the sequence, specifying the 5' to 3' orientation) [blank4]
