What does the charge of DNA have to do with DNA fingerprinting?
DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.
How does DNA charge affect movement in electrophoresis?
DNA molecules have a negative charge due to the phosphate groups in their backbone. In electrophoresis, an electric field is applied across a gel matrix, causing DNA fragments to migrate towards the positive electrode. The negatively charged DNA molecules are attracted to the positive electrode and move through the gel at different rates based on their size, with smaller fragments moving faster than larger ones.
Why does DNA wraps around histone?
DNA wraps around histone proteins to form a structure called a nucleosome. This packaging allows for compaction of DNA, making it more efficient for storage in the cell. Additionally, the interaction between DNA and histones plays a role in gene regulation by influencing accessibility of DNA for transcription factors.
Why the charged balloon wiill be attracted to the charged glass rod?
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other
Cations are attracted to cathod or anode?
Cations are positively charged ions, and they are attracted to the cathode in an electrolytic cell. At the cathode, cations gain electrons and get reduced.

What is the net charge of DNA?
The net charge of DNA is negative.
If an object a is attracted to a magnet does the abject a have a charge?
Charge is an electric field, A magnet has a magnetic field. If an object is attracted by a magnet it does not signify whither or not it has a charge.
What charge do the phosphates impart to DNA?
Phosphates impart a negative charge to DNA.

What would be attracted to a proton?
Electrons would be attracted to a proton due to their opposite charges. The positive charge of the proton exerts an attractive force on the negatively charged electron, causing them to be attracted to each other.
Does a A molecule with a positive charge attracted to another molecule with a positive charge?
Nope
What atom gives DNA its charge?
The sugar-phosphate backbone of DNA gives it an overall negative charge.
What subatomic particles are electrons attracted to?
The electron has a negative charge, so it would attract and be attracted by particles of opposite/unlike charge (positive charge) such as protons.
What part of DNA gives the molecule a negative charge?
The phosphate groups in the DNA molecule give it a negative charge.
Does DNA possess a negative charge?
Yes, DNA possesses a negative charge due to the phosphate groups in its structure.
Which subatomic particle will be attracted by a positive charge object?
Electrons because of their opposite charge.
