You are given a circular DNA molecule to analyze that is 3,000bp
(3 Kb) long. You proceed to treat the DNA molecule with different
cutting enzymes and then you run the individual reactions on a gel.
The following gel is produced with each column representing a
different reaction (lane). In lane 1 a molecule weight ladder is
run. In lane 2, the circular DNA is NOT treated with any enzyme. In
lane 3 the DNA is treated with an enzyme...
A linear piece of DNA has the following restrictions sites: Xbal Noti Psti EcoRi 2 kb 4 kb -> 1 kb 2 kb 3 kb You decided to set up an experiment where you added one of these restriction enzymes to this DNA. After this DNA was digested with that restriction enzyme, you separated the resulting fragment(s) using agarose electrophoresis. After the gel was stained with ethidium bromide, you observed the following gel (the DNA ladder is your reference standard...
. Using the figure of the gel below,
draw in the DNA bands in the left lane that would appear from the
DNA of the person described in the question above. The right lane
contains a molecular weight standard.
the questions are
When circular DNA is sequenced, the
nucleotide base pairs are numbered starting from an fixed position
on the DNA, all the way around, usually in a clockwise
manner. a DNA molecule that is 3133 base pairs long is...
1) Imagine that you had two restriction enzymes and a known segment of linear DNA 160 kb long: Enzyme A cuts at location(s): 20 kb, 45 kb 70 kb and 110 kb. Enzyme B cuts at location(s): 15 kb and 140 kb. Based on this information, first construct a linear map of this DNA showing the positions of these restriction enzyme cut sites. In the space below.draw what the gel would look like given the following lanes: (8 points total)...

someone explain throughly on how to find a-c??? thanks!!!
The following question will provide practice in interpreting and analyzing gel results. 5. You obtained the DNA electrophoresis gel below. Three samples of lambda phage DNA were digested with 3 different restriction enzymes and the digested DNA was applied to the gel in lane 4 and the bands were visualized. The Hind Ill digest was used as a molecular weight standard marker and produced 6 DNA fragments of known size:...
Sketch the predicted migration pattern on an agarose gel of the following DNA samples: (1) Undigested pET15b plasmid; (2) pET15b digested with the EagI restriction enzyme; (3) pET15b digested with NdeI and AhdI (see pET15b vector map for location of these enzyme cutting sites). Include in your sketch a DNA base-pair ladder from 0 to 10,000 bp with 1000 bp increments. Label each band in the DNA ladder with the known size (in base-pairs), and estimate the size of the...
III. Subclone the gene into plasmid, extract the plasmid DNA. 5. You know that your insert (gene of interest, GOI) is flanked by the EcoRI sites, which makes this restriction enzyme a perfect candidate to cut out your gene. You also know that the GOI has a unique BamH1 restriction site. After subcloning the PCR product into the plasmid, a purified DNA preparation of the plasmid is digested to completion with BamHI restriction endonuclease. In separate reactions, the same preparation...
Aliquots of a 7.8-kilobase (kb) linear piece of DNA are digested with the restriction enzymes PvuII, HincII, ClaI, and BanII, alone and in pairs. The digestion products are separated by gel electrophoresis, and the size of each fragment is determined by comparison to size standards. The fragment sizes obtained, in kilobase pairs, are given below. Draw a diagram of the 7.8-kb fragment, showing the location of the restriction sites for each enzyme. a.Digestion with PvuII: 1.3 kb, 6.5 kb b.Digestion...
Hi I have a problem with number 5, it involves gel
analysis results. There are 2 parts, a,b,c. For A Im sure you need
to make a graph with distance in (cm) on the vertical axis and
log10 bp on the horitzontal. I need help figuring out where to
start and what to do. Please help!
