Given the following double-stranded fragment of DNA:5'- ACTTGGCAGGCCTTCGATCC-3'3'- TGAАССGTCСGGAAGCTAGG-5'A hypothetical restriction endonuclease recognizes a 6bp sequence with two-foldsymmetry (typical for restriction enzymes) found in this fragment and catalyzescleavage of this DNA on both strands between GG nucleotides within the recognitionsequence. This nuclease exhibits b-type cleavage (atypical for restriction enzymes).Draw the double-stranded sequence of each fragment after cleavage showing anyphosphates left on the ends.

You 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?

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.
This is part of the Escherichia coli DNA sequence that contains an inverted repeat.
