DNA is negatively charged bereason of the existence of phosphate teams in nucleotides.

You are watching: Why does dna have a slight negative charge

The phosphate backbone of DNA is negatively charged, which is due to the visibility of bonds developed in between the phosphorus and oxygen atoms.

In DNA structure, a phosphate group comprises one negatively charged oxygen atom, which is responsible for the whole strand also of DNA to be negatively charged.

Let’s discover even more around DNA and also its structure.

What is DNA?

DNA- Deoxyribonucleic Acid is an inherited product, which is uncovered in eextremely single living species from unicellular amoeba to multicellular organisms – plants, animals, birds, mammals and also people.

DNA – Deoxyribonucleic Acid is an organic compound that has actually a distinct molecular framework and is found in both prokaryotic cells and also eukaryotic cells. These hereditary products are made up of nucleotides molecules.

DNA was first established and also uncovered by Johannes Friedaffluent Miescher, a Swiss Biologist in the year 1869, in the time of his examicountry of white blood cells.

The structure of a DNA molecule is a double helix, which was later found by James Watson and also Francis Crick and also later showed that DNA molecules are mostly responsible for collecting and maintaining hereditary indevelopment in all living organisms.

Structure of DNA


The framework of DNA defines the standard hereditary makeup of all stays on the earth earth. Deoxyribonucleic acid is a molecule written of nitrogenous bases, sugar molecules and also phosphate teams.

The framework of DNA is double helix. DNA comprises two strands, which are discovered coiled or wrapped roughly each various other and also create rather similar structures to a twisted ladder. Each strand also possesses a backbone, which is made of alternating sugar (deoxyribose) and phosphate teams.

DNA is composed of nucleotides, which contain:

A phosphate groupA sugar groupFour various types of nitrogen bases – Adenine (A), Thymine (T), Guanine (G) and also Cytosine (C).

Types of DNA

There are three different DNA types:

A-DNA — Right-handed helixB-DNA — Right-handed helixZ-DNA — Left-handed helix

We humans have B-DNA, right-handed double-helical framework.

Functions of DNA
