You have just produced DNA fragments from a 12 Kb bacterial plasmid using a pair of restriction enzymes, A & B. Some of the fragments were made by a single enzyme, others by both enzymes together. Data from the experiment are below. A only: 4 Kb and 8 Kb B only: 5.5 Kb and 6.5 Kb A & B: 1 Kb, 2.5 Kb, 3 Kb, and 5.5 Kb. which of the A&B fragment combined would make up the 4 Kb A only fragment

You have made a mouse genomic DNA library by cutting mouse DNA with BamHI, ligating the mouse DNA fragments into the vector pBR322 at the BamHI site and then transforming the plasmids into E. coli. The pBR322 plasmid is 4.3 kb long and has a single site for the restriction enzyme BamHI. You select another bacterial colony and extract plasmid DNA. Assume that you have a 2 kb cloned fragment in this plasmid. If you digest the plasmid with BamHI,...

Construct the physical map of a DNA molecule from which fragments of different sizes were generated after digestion with the following restriction enzymes: -ApaI: generates a 5.8 kb fragment -BamHI: generates two fragments of 2.5 and 3.3 kb -PstI: generates a 5.8 kb snippet -ApaI / BamHI: generate three fragments of 1.3, 2.0 and 2.5 kb -ApaI / PstI: generate two fragments of 1.0 and 4.8 kb -BamHI / PstI: generate three fragments of 0.3, 2.5 and 3.0 kb -ApaI...

Question 7 Use the illustration below to answer the next 5 questions.   A plasmid called pKSU1 is shown on the left.  A piece of genomic DNA isolated from another organism is on the right.  The cut sites for three restriction enzymes are shown (SelI, HerII, HimIII) for both. Your goal is to insert the gene of interest from the genomic DNA into pKSU1. Which restriction enzyme(s) would you digest the genomic DNA with to obtain a smaller fragment that contains the gene of...

A circular plasmid of 6.0 kB was cleaved with the restriction enzymes EcoRI, BamHI and PstI.  Cleavage with each enzyme alone gave a single band of 6.0 kB for BamHI and PstI, and a single band of 3.0 kB for EcoRI.  When BamHI and PstI were used together for the digest, bands of 1.5 and 4.5 were observed, and when BamHI and EcoRI were used together only the 3.0 kB band was observed.  What do you predict will be the pattern generated by...

See experiment info below The NaOH used in this lab should have been 0.1M, since you were to make it as such (see Step 15 in lab document). Compare your standardized average molarity of NaOH in this lab to 0.1M. How do the values compare? How close was your NaOH dilution to actually being 0.1M NaOH? Calculate your percent error against the average standardized value from this lab. (You must show all work to receive credit.) step 15- Prepare an...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
