9. On Worksheet 16.IIIB is a restriction map of bacteriophage lambda. You digest some lambda DNA with the enzymes BamHI and HindIII separately and then load the fragments into an agarose gel and perform electrophoresis. Next, you perform a Southern analysis using the 4,878-bp EcoRI lambda fragment as a probe. a. Draw a picture of the electrophoresis gel, using the outline of the stained electrophoresis gel in Worksheet 16.IIIB (the two smallest HindIII fragments will run off the gel.) b....
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...
For each problem draw each digest listed as well as a final figure with each restriction site indicated 1. Construct a restriction map of a linear fragment of DNA, using the following data. Your map should indicate the relative positions of the restriction sites along with distances from the ends of the molecule to the restriction sites and between restriction sites: DNA Sizes of Fragments (bp) uncut DNA: 10,000 DNA cut with EcoRI: 8000, 2000 DNA cut with BamHI: 5000,...
Hello,
I came across this question and I am confused on where to
start.
Restriction mapping of a linear piece of DNA reveals the following EcoRI restriction sites. Site 1 Site 2 _2kb 4kb 5kb 1. This piece of DNA is cut by EcoRI the resulting fragments are separated by gel electrophoresis, and the gel is stained. Draw a picture of the bands that will appear in the gel below 2.If a mutation that alters EcoRI site 1 occurs in...
Questions 9-12 deal with SSR loci in Sam's genome. Remember that SSRs (simple sequence repeats) are tandem (next to each other) repeats of short sequences (a few bp). Such tandem repeats are located at specific sites scattered throughout the genome. Individuals vary in the number of repeats at each site sites can have up to 100 repeats. Each locus with the same repeats is called an SSR ocus DNA was extracted from Sam's white blood cells and cut with a...
One strand of a DNA sequences is given below. Find the
EcoRI sites and indicate the cutting site with an arrow. Count the
number of bases in each fragment.

Now determine the sizes of the fragments generated after digesting the r-plasmid with each of the restriction enzymes or combination of restriction enzymes. r-plasmid digested with Pstl r-plasmid digested with EcoRI r-plasmid digested with both Pstl and EcoRI Question 8. (3 pts.) Use this information to determine the relative placement of these restriction sites in the r-plasmid, and then draw restriction site maps of the vector and the r-plasmid on the following circular chromosome templates. The map should show the...
1. You perform a restriction endonuclease assay on an uncharacterized DNA molecule, using Pstl, Sall, and Xhol. When you run the DNA on a 1% agarose gel, you obtain the following information regarding fragment number and length (all lengths are in bp): Pstl (P) 700 200 Sall(s) 600 300 Xhol (X) 500 350 50 Pstl + Sall (P+S) 600 200 100 Pstl + Xhol (P+X) 500 200 150 50 Sall + Xhol (S+X) 500 250 100 50 Solve the following...
. 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. If a restriction enzyme cuts a circular plasmid twice, how many fragments would you see on the gel? 2. How would you estimate the total number of base pairs in a plasmid by looking at the DNA fragments of the digested plasmid on a gel? 3. If a linear 1kb DNA fragment has a restriction site that is located 50 bp from one end of the plasmid, what would you expect to see if the digested and undigested DNA...
