A circular DNA molecule digested with a restriction enzyme which has 4 recognition sites on that molecule will result in how many fragments?
Homework Answers
It will results in 4 fragments.
Explanation:- restriction enzymes cuts the DNA molecules and divide it into fragments. The restriction enzymes (eg EcoRI) recognize the specific site on the DNA known as recognition site and cuts the DNA near or at the restriction site. So if there is a liner DNA molecule having 4 recognition sites, the restriction enzymes cut the dna at those recognition sites and results into 5 fragments of dna .
In case of circular dna having 4 recognition sites, the restriction enzyme digest the dna and results in 4 fragments of that dna
If you find my answer useful please give me a thumbs up. Thank you

A linear DNA molecule that is 3250 bp long is digested with restriction enzyme A alone, restriction enzyme B alone, or a combination of enzymes A and B to produce the following fragment sizes. Construct a restriction map of the DNA fragment. How many times does enzyme A cut the linear DNA molecule? If you are unable to place both enzymes A and B on the map, show one possible arrangement of enzyme A cognition sites on the DNA molecule.

A 10 kb linear DNA molecule was digested with restriction enzyme EcoRI (E) and two fragments were produced of sizes 6 kb and 4 kb. The restriction enzyme HaeIII (H) also produced two fragments of sizes 9 kb and 1 kb. When the two enzymes HaeIII and EcoRI were used together, three fragments were produced of sizes 1 kb, 3 kb, and 6 kb. A 4 kb long cloned genomic probe from this region hybridized to the 3 kb and...

A linear DNA molecule was digested with restriction enzyme EcoR I (E) and three fragments were produced of sizes 7.3 kb, 4.0 kb and 3.4 kb. The restriction enzyme BamH I (B) produced three fragments of sizes 7.9 kb, 4.8 kb and 2 kb. When the two enzymes EcoR I and BamH I were used together, five fragments were produced of sizes 6.5kb, 4kb, 2kb, 1.4kb, and 0.8kb.

The figure below shows a restriction map of a segment of a DNA molecule. Eco refers to locations where the restriction endonuclease EcoRI cuts the DNA, and Pst refers to locations where the restriction enzyme Pst cuts the DNA. Potential restriction sites are numbered 1-6. Distances between restriction sites are shown on the bottom scale in base pairs (bp). The thick line represents the part of the molecule that has homology with a probe. Eco Pst Eco Pst Eco Pst...
