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.
What else can I help you with?
How does halving a sample affect the weight of the sample?
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
Why are CD sample rates 44.1 KHz?
because human hearing is about 20kHz. so according to sample theorem, it has to be twice..

Can I ask for a sample emcee script for recognition or graduation day of a high school class?
yes i wanted to have a sample script for emcee in a high school graduation
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.
Why do you place the wells near the negative electrode of the gel chamber?
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.
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
Can the variance of a sample be negaTIve?
No.
What the precaution on negative stain?
One precaution when using negative staining is to ensure that the sample is completely dry before applying the stain. Any presence of water can affect the staining process and result in inaccurate visualization of the sample. Additionally, it is important to handle the stain carefully, as some negative stains can be toxic or corrosive.
Can the sample mean be a negative number?
Yes, it can.
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
Can the sample mean in statistics be either positive or negative?
It can have either a negative or positive trend

What is meant by coliform negative in 0.1g?
"Coliform negative in 0.1g" refers to the absence of coliform bacteria in a sample weighing 0.1 grams. Coliforms are a group of bacteria commonly found in the environment and are used as indicators of water quality and sanitation. A negative result indicates that the sample is likely safe from contamination by fecal material or pathogens. This is important for assessing the safety of food, water, or environmental samples.
How is hyponatremia diagnosed?
Hyponatremia is diagnosed by acquiring a blood sample, preparing plasma, and using a sodium-sensitive electrode for measuring the concentration of sodium ions.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
