Name and discuss a source of error in performing and evaluating gel electrophoresis

Biology
1 answer:
Sergio039 [100]3 years ago
7 0

Answer:

Contamination of a sample

Explanation:

Gel electrophoresis is  a method used in molecular biology for DNA analysis. This method includes the separation of DNA fragments through the gel according to their size or shape.

One of the major source of error is contamination of the DNA sample. This refers to the presence of foreign DNA in the sample of interest. As a consequence, the gel will have more bands.

Another errors might appear as a result of wrong concentration of the gel, wrong buffer pH, high/low concentration of dye etc.

Review the data table. What conclusion can be drawn from the data shown?
joja [24]

Answer:

B) Styrofoam is a good insulator.

Explanation:

When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.

So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.

Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to
steposvetlana [31]

Bacterial flagellum is composed of protein flagellum which looks like hollow tube. It passes through protein rings (basal body rings) in the cell's membrane that act as bearings. Flagellum is long, filamentous and it rotates via motor which is located on the inner cell membrane. The motor is powered by proton motive force (flow of protons through the membrane due to a concentration gradient).
