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".

What cause the DNA fragments to move through the gel?
DNA is negatively charged and a current is running through the gel with the positive pole and the foot of the gel run, so the DNA migrates from the head of the run towards its oppositely charged pole.
Properties of DNA fragments which allow them to be separated from each other during gel electrophoresis?
They are negatively charged and are of different sizes
What functional group in the DNA structure causes it to move only toward the positive poles?
The negatively charged phosphate groups of the DNA causes them to move only towards the positive poles
DNA molecules have what kind of charge?
DNA MOLECULES HAVE A NEGATIVE CHARGE.
Why all DNA molecules move in the same direction in an electric field?
DNA molecules are negatively charged. When places in an electric field, like in an gel during the process of electrophoresis, they all move toward the positive electrode.
Is DNA negativly or positivly charged?
DNA is negatively charged due to the phosphate ions in its structure.
Why is DNA sticky when extracted?
While glass is positively charged, the oxygen in the DNA, which is negatively charged, is attracted to it, making it "sticky". DNA is mostly composed of oxygen meaning that it can stick to pretty much anything.
Once DNA has replicated it condenses when negatively charged phosphate groups interact with positively charged protein molecules known as?
Histones
Do chromosomes consist of both DNA and protein?
Yes, DNA is packaged into the tiny spaces of chromosomes through proteins called histones. The DNA along with histones is called chromatin. The histones are positively charged and DNA negatively charged.
How DNA binding to the nylon membrane?
Some membranes are positively charged and therfore they can electrostaticaly bind negatively charged DNA. Exposing of membrane with electrostaticaly bound DNA to UV light will make make covalent binds between membrane and DNA.
What is the role of NaCl and edta in DNA isolation?
NaCl provides Na+ ions that will block negative charge from phosphates on DNA. Negatively charged phosphates on DNA cause molecules to repel each other. The Na+ ions will form an ionic bond with the negatively charged phosphates on the DNA, neutralizing the negative charges and allowing the DNA molecules to come together
Once DNA has replicated it condenses when negatively phosphate groups interact with charged protein molecules knows as?
histones
Is lighting negatively charged or positively charged?
Negatively charge
Which of the following particles is negatively charged?
An electron is negatively charged.
Will an object that is negatively charged what will it attract?
Negatively charged objects
Are electron negatively charged atoms?
No. An electron is negatively charged but it is not an atom. It is a subatomic particle and the negatively charged component of an atom.
What is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
histone
