Placing the wells near the negative electrode in a gel electrophoresis setup allows the negatively charged DNA or RNA samples to migrate towards the positive electrode. This orientation facilitates the separation of nucleic acids based on size, as smaller fragments move faster through the gel matrix than larger ones. Additionally, positioning the wells near the negative electrode minimizes the risk of sample loss due to diffusion before the electrophoresis begins.

Why is it important for the sample wells to be near the negative electrode?
Placing the sample wells near the negative electrode ensures that DNA fragments migrate towards the positive electrode, allowing for separation based on size during gel electrophoresis. This setup helps maintain consistency in the direction of movement and ensures accurate sizing and visualization of DNA bands.
What would happen if the electrodes were plugged into the wrong outlet during gel electrophoresis?
DNA migrates from the black (negative) terminal to the red (positve) if you place your DNA in the wells adjacent to the red terminal in would in a short time migrate off the end of your gel into the running buffer. Most people who run DNA gels have done this at least once.
What is The piece of plastic that is used to make wells in an agarose gel called?
The piece of plastic used to create wells in an agarose gel is called a comb. It is inserted into the gel before it solidifies, creating indentations that serve as wells for loading samples during gel electrophoresis. Once the gel is set, the comb is removed, leaving behind the wells for sample application.
What are some potential designs for a gel electrophoresis chamber?
a box and a chamber and a lid and a comb A gel electrophoresis can be made two different ways---horizontal or vertical. I'm doing a project with it right now, and honestly, I prefer the horizontal. I don't know how the vertical works, but the horizontal is pretty much a box inside a box with the lid and comb. The bigger box, or your chamber, should be large enough to fit all the wiring on each ends of it, and the smaller box, or the box, in the middle. Your box should have two removable walls on the ends in which the wells are facing, and slits on one end for the comb to go into. You should put the comb in and fill the box up with the gel, and when it dries, you take the comb out and take off both walls. The charge can then run through the walls and to the other side of the chamber.

Why is it important to position the sample wells near the negative electrode?
1. DNA is negatively charged by placing the sample wells closest to the negative electrode we can give the DNA more room to spread out in accordance to its size and charge. The amount the DNA moves from the well is directly linked to its charge and size. Since DNA is only negatively charged leaving space for the DNA to move in the positive direction would be a waste of space because it is not possible.
The place where refining of oil takes place?
oil wells
Who was influenced by Ida B Wells?
Ida B Wells influenced everyone who read her newspaper articles about the lynchings that took place.
What electric charge do you hook up closet to the wells?
You should hook up an electric charge of the same polarity (positive or negative) as the wells to repel the charged molecules or particles towards the wells. This helps in efficient separation and collection of the desired components in the well.

Why digging of large number of tube wells is restricted in urban areas?
Digging a large number of tube wells in urban areas can lead to groundwater depletion, saltwater intrusion, and land subsidence. This can significantly impact the local hydrology, water quality, and infrastructure. Therefore, restrictions are put in place to ensure sustainable water management and prevent negative environmental consequences.
Which of these is a negative consequence of the oil industry in Texas?
a it create jobs on oil wells and in refineries b there can be oil spills when the oil is transported from one place to another c the oil can be use to create energy d the oil comes from under the ground
What were wells used for in the middle ages?
Water. Only place besides river to get water.
