The picture above represents an agarose gel that was used to analyze plasmid DNA after it was cut with the restriction enzyme HindIll. The plasmid was incubated with Hindill until all of the available Hindlll cut sites were cut by HindIll. After running the sample on the gel, three bands were detected (Note that there are three wells shown at the top of the gel for loading samples, however, only the middle well was loaded with sample). Based on this...

Chromosomal and plasmid DNA can be cut into manageable pieces by
restriction enzymes. Using agarose gel electrophoresis, the DNA
fragments can be separated on a gel, based on their lengths. In
order to see the fragments, a stain is typically added to the gel.
The size of each fragment can be determined by comparing each one
to a DNA molecular weight marker of known size.

Cloning / Subcloning When subcloning engineering new plasmids, by inserting new DNA fragments (inserts) me plasmids (now called a vector because it will carry your gene of interest) it is important to considering existing genes / DNA elements. If a site is in the middle of a gene, you could lose or destroy that gene. If there are multiple sites for an enzyme, when you paste them together, multiple possible outcomes can arise. This is undesirable, because it confounds verification...

Can you pleasee answer these questions: If we performed electrophoretic separation (AGE) of human genomic DNA (buccal swab extraction), and we didn’t perform any restriction digestion, answer the following: 1. How many bands do you expect to see in each lane where genomic DNA is loaded? 2. Why do you see bands above the molecular marker? 3. How many wells do you see on the gel? How many of them are used in the experiment (i.e. have loaded samples)? Thank...

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:...

(1) You start with the pUC18 plasmid that is a -2.7 kb circular DNA molecule. The multiple cloning site (i.e., polylynker) has unique restriction sites in the following order: HindIII, BamHI, EcoRI. Recall that unique restriction site means that these sites are only found once on...
