DNA is negatively charged due to the negatively charged phosphate ions in its structure.
DNA carries 2 negative charges per base pair (whose length is 0.34 nm).
As a title of example, the human DNA has about 6 thousands of million (6 x 10^9) base pairs. This gives a total charge of 12 thousands of million negative charges (12 x 10^9 negative charges), and a total length of about 2 meters.

What does salt do in DNA extraction?
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
DNA molecules have what kind of charge?
DNA MOLECULES HAVE A NEGATIVE CHARGE.
Which of the following best describes how scientists use gel electrophoresis?
Gel Electrophoresis is the technique for sorting DNA molecules based on their number of base pairs by running a current through the gel. The sample travels opposite of the direction of the electrical charge since DNA is negatively charged. Using a certain primer you can identify the BP of the sample.
What does salt do in extrating DNA?
Salt provides the DNA with a favorable environment; it contributes positively charged atoms that neutralize the normal negative charge of DNA.
Why is DNA negatively charged?
DNA is negatively charged because of the phosphate group that is in each nucleotide. DNA also has a negative charge because of the phosphate icons in its chemical "backbone".
Is plasma a gas with an electrical charge?
Yes, a plasma is a gas with an electrical charge.
What kind of elicctcal charge do protons elictrons and nutrons have?
Protons have an electrical charge of +1. Neutrons have an electrical charge of 0. Electrons have an electrical charge of -1.
What electrical charge does a neutron contain?
A neutron carries no electrical charge
What is the electrical charge of aluminium?
The electrical charge of aluminum is +3.
What is proton electric charge?
A proton has a positive electrical charge and an electron has a negative electrical charge.
What does salt do in DNA extraction?
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
Which charge is the DNA attracted to?
Since DNA has a phosphate group it has a negative charge and so it is attracted by a positive charge.
What electrical charge do protons neutrons and electrons have?
Protons have a positive charge, neutrons have no charge, and electrons have negative charge.Neutrons do not carry an electrical charge:)A proton has a positive charge. Remember, NEUTRon = NEUTRal. Proton = Positive. The electrical charge of a proton is 1.6x10^-19 which is equal and opposite to the electrical charge of an electron which is -1.6x10^-19.
What is a neutrons electric charge?
A neutron does not have an electrical charge. It is electrically neutral, hence its name.
Does any object have electrical charge?
Yes, some objects have an electrical charge.
An electrical charge is the result of the flow of?
An electrical charge is the result of the flow of electrons.
Difference between electrical current and electrical charge?
current is the flow of charge.
