Yes
The phosphate groups in the DNA molecule give it a negative charge.
The DNA backbone, are made of alternating sugars and phosphate groups.
The phosphate backbone of the DNA molecule is most exposed to the watery environment in the cell. The phosphate groups are hydrophilic and interact with water molecules, making them the most accessible part of the DNA molecule in the cellular environment.
DNA is negatively charged because it contains phosphate groups in its structure, which have a negative charge. These phosphate groups are part of the backbone of the DNA molecule, contributing to its overall negative charge.
The DNA backbone, are made of alternating sugars and phosphate groups.
On the exterior linking the sugar backbones together.
A phosphate group is a part of a molecule (i.e. group) with the formula PO4. Depending on the molecule it is part of it can be either inorganic phosphate or organic phosphate. Phosphate groups are essential to many biochemical processes (e.g. ATP for energy storage, phosphorylation of DNA to inhibit/enable gene expression).
phosphate molecule
A DNA molecule with five base pairs would have 5 phosphate groups in its backbone. Each nucleotide in the DNA molecule contains one phosphate group, so a DNA molecule with five base pairs would have a total of 5 phosphate groups in its structure.
The triphosphate group of the deoxynucleoside triphosphate molecule provides the energy required for DNA synthesis. When one of the phosphate groups is cleaved, it releases the energy necessary for the formation of phosphodiester bonds between nucleotides during DNA replication.
The deoxyribose is located in the backbone of the DNA molecule, forming the sugar-phosphate backbone along with the phosphate groups.
