The recognition sequence for the restriction enzyme BamHI is '5-GGATCC-3' on one strand. What would be the recognition site on the complementary strand?
The restriction enzyme BamHI cuts the sequence GGATCC, leaving the 5' overhang and a four-base sticky end. Draw the structure of this sequence after it has been cleaved by this enzyme. Abbreviate the nitrogenous bases fully but completely draw the backbone structure of both strands.

False 2.In general, restriction enzymes that recognize four nucleotides have higher probability to produce more DNA fragments than those enzymes that recognize six nucleotides. A. true B. false 3. Which of the following sequences are palindromes? A. 5' TGGCCA 3' B. 5' GAAAAG 3' C. 5' CGATGG 3' D. 5' GACGAC 3' 4. Below are the possible...
Suppose you digest the genomic DNA of a particular organism with
the restriction enzyme SauA. Then you ligate the resulting fragment
into a unique BamHI cloning site of a plasmid. The sequence of the
restriction sites and position of cleavage is shown below
Note: X and Y and their complementary bases Z and Y’
respectively can be any base (A,C, G, or T)
1) As you can see, ligation is possible because the two restriction
enzymes produce compatible sticky ends....
EcoRI is a common restriction enzyme used in cloning experiments. Its restriction sequence is G’AATTC. The strand is cut at the position of the apostrophe. The 50 base pair sequence shown below contains one or more EcoRI sites. Find them and circle them. Then count the resulting size (in base pairs – bp) of the DNA fragments (pieces) left over after using EcoRI to cut this DNA sequence. Circle the EcoRI sites in the sequence below. 1- ggagaattcgctgtacgaggttaaccccgatgccATGGCATGAATTCGTG -50 List...
