Gel electrophoresis is a process used in laboratories to separate macro molecules. Mark the statements that are true as related to gel electrophoresis. An electrical charge is applied to the gel plate The pieces of DNA move due to electrical charge and also size A sample of the DNA is placed in a small well and a charge is applied The pieces of DNA or bands are stained to be visible Running a "gel" can be used to compare a perpetrators DNA to the DNA found at a crime scene.

Expert Solution

Answer:

Gel electrophoresis is a process used in laboratories to separate macro molecules. Mark the statements that are true as related to gel electrophoresis.

An electrical charge is applied to the gel plate - Correct (In gel electrophoresis, an electrical charge is applied to the gel plate and DNA migrates based on charge and size)
The pieces of DNA move due to electrical charge and also size - Correct (migration rate of the macromolecules like DNA, RNA etc. are affected by their size, charge and conformation).
A sample of the DNA is placed in a small well and a charge is applied - Correct (DNA is loaded into pre-cast wells in the gel and a current or electric charge is applied.)
The pieces of DNA or bands are stained to be visible - Correct (sample is stained with Ethidium Bromide which is a DNA intercalating agent to visualize the bands)
Running a "gel" can be used to compare a perpetrators DNA to the DNA found at a crime scene -Correct (gel electrophoresis is used in forensic analysis to isolate and compare and analyze DNA)

In genetics when using gel electrophoresis there are many decisions. If you want to separate fragments that are very close in size you should use a higher percentage of agarose. The power supply has two settings for voltage, 120V or 160V. It also has a timer that has 2 settings 15 minutes and 90 minutes. If you would be running whole genomic DNA samples you recently extracted and the fragments would be about 30 kb in size. If performed a number...

-Describe the process of gel electrophoresis. How would the distance that each DNA fragment travelled on your gel change if you were to make the gel using a higher percentage of agarose (for example 3%)? Explain -Describe the steps involved in a polymerase chain reaction (PCR), including the changes in temperature that are performed by the thermocycler and the purpose of each temperature change.

Be specific with what you would expect to see in the various lanes of the gel if a ladder, comtrol ( digested plasmid + insert without ligase) and sample ( digested plasmid + insert with ligase) were run.
