Step-by-Step Analysis
Interpreting the question, we are asked to identify which feature of restriction enzymes is most useful for creating recombinant DNA.
Option 1: 'leave a sticky residue on the cut ends of the DNA.' This describes sticky ends, which result from staggered cuts and are indeed highly useful for ligating DNA fragments with complementary overhangs. However, the statement is somewhat awkward in wording—while it ......Login to view full explanationLog in for full answers

You are trying to insert a human insulin gene into a bacterial plasmid. You cut the human DNA with the restriction enzyme EcoRI (which produces a specific sticky end) and you cut the plasmid with a different enzyme, BamHI (which produces a different sticky end). You then mix them with DNA ligase. What will be the result?
Question at position 5 In two separate reactions you digestion a large piece of DNA (700 kB). One you digest with RsaI (a 4-base cutter), the other you digest with BamHI (a 6-base cutter). You then run them on an agarose gel but forgot which lane was which. The sample digested with RsaI (assume complete digestion) is most likely to be _____________.The lane with the larger fragmentsThe lane with the smaller fragmentsThere is no way to tellThe lane that has visible fragments rather than a smearThe lane with the least number of fragments
Question28 How many times will the restriction enzyme DdeI, which has a recognition site of 5'- C/TNAG - 3', be expected to cleave a plasmid that is 5,822 base pairs in length? Round your answer to the nearest whole number and type it in the box provided below. Do not include punctuation in your answer. For example, if your answer is 1,000 type in 1000. DdeI will cleave the plasmid [input] time(s). Maximum marks: 1 Flag question undefined
