Since DNA has a phosphate group it has a negative charge and so it is attracted by a positive charge.

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.
Why does DNA wraps around histone?
DNA has a net negative charge (which is due to the phosphate backbone) and is Acidic nature and histones which have a pI of ~10 are basic and overall have a positive charge (histones are right in argenines and lysines). Opposites attract, + and - are attracted. :) hope this helps
What is the purpose of the electrical current in gel electrophoresis?
The electrodes are able to pull the fragments towards the ends of the gel. If you're using DNA, which has a negative charge, it will be attracted to the positive electrode.
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.
Cations are attracted to cathod or anode?
DNA is neither cathode or anode, but it is negatively charged, so the DNA molecules will rn from anode to cathode
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.

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 does salt do in DNA extraction?
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.

What would be attracted to a proton?
Electrons are attracted to protons. This is because protons have a positive charge and electrons have a negative charge. Due to the laws of magnetics these opposing charges will attract.
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
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.
