Conclusion – Why Is DNA Negatively Charged?

In conclusion, DNA is negatively charged because of the presence of phosphate groups in nucleotides. The phosphate backbone of DNA is negatively charged, which is due to the presence of bonds created between the phosphorus and oxygen atoms. In DNA structure, a phosphate group comprises one negatively charged oxygen atom, which is responsible for the entire strand of DNA to be negatively charged.

Why is DNA Negatively Charged?

DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions necessary for the development and functioning of all known living organisms. It consists of two long chains, known as strands, that coil around each other to form a double helix. The DNA is negatively charged. In this article, we will learn the answer to “Why is DNA Negatively Charged,” and the structure and function of DNA in detail.

What is DNA?

DNA is a genetic material that is present in every single organism from unicellular to multicellular organisms. It carries genetic information about a particular species. The full form of DNA is Deoxyribonucleic acid. DNA was discovered by a Swiss Biologist Johannes Friedrich Miescher, in the year 1869. Structurally, DNA is a double helix formed by two complementary strands of nucleotides, each containing a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, and guanine)....

Structure of DNA

DNA or deoxyribonucleic acid is double helical polynucleotide chains. It contains genetic code that is unique for every individual. Genetic code is composed of three DNA nucleotides (codon) that correspond with a specific protein that is responsible for making different Structures, Enzymes & organs of our body. Now let’s study more about the structure of DNA. DNA is composed of a sugar-phosphate backbone and nitrogenous base pairs. There are two types of nitrogenous base pairs:...

Why is DNA Negatively Charged?

DNA is negatively charged because of the presence of negatively charged phosphate groups. In the phosphate group there is single negatively charged oxygen, which makes the entire DNA negatively charged. Negativity of DNA helps in joining two strands of DNA together to form a double helical structure. Now let’s make the concept more clear about Double helical structure of DNA....
